The Asus Zenbook Duo (UX8406MA) has a keyboard which can be
placed on the laptop to connect it via USB, or can be removed from the
laptop to reveal a hidden secondary display in which case the keyboard
operates via Bluetooth.
When it is placed on the secondary display to connect via USB, it emits
a keypress for a wireless disable. This causes the rfkill system to be
activated disconnecting the current wifi connection, which doesn't
reflect the user's true intention.
Detect this hardware and suppress any wireless switches from the
keyboard; this keyboard does not have a wireless toggle capability so
these presses are always spurious.

this configuration, all command submissions to PMFW are treated as

To address this issue, the CPU ID association for the new platform needs

Make the acerhdf driver use the .should_bind() thermal zone
callback to provide the thermal core with the information on whether or
not to bind the given cooling device to the given trip point in the
given thermal zone. If it returns 'true', the thermal core will bind
the cooling device to the trip and the corresponding unbinding will be
taken care of automatically by the core on the removal of the involved
thermal zone or cooling device.
The previously existing acerhdf_bind() function bound cooling devices
to thermal trip point 0 only, so the new callback needs to return 'true'
for trip point 0. However, it is straightforward to observe that trip
point 0 is an active trip point and the only other trip point in the
driver's thermal zone is a critical one, so it is sufficient to return
'true' from that callback if the type of the given trip point is
THERMAL_TRIP_ACTIVE.

The dell-uart-backlight driver supports backlight control on Dell All In
One (AIO) models using a backlight controller board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Now the first AIO has turned up which has not only the DSDT bits for this,
but also an actual controller attached to the UART, yet it is not using
this controller for backlight control.
Use the acpi_video_get_backlight_type() function from the ACPI video-detect
code to check if the dell-uart-backlight driver should actually be used.
This allows reusing the existing ACPI video-detect infra to override
the backlight control method on the commandline or with DMI quirks.

Change the Kconfig dependency so that it doesn't require both I2C and SPI
subsystems to be built. Make a few small changes to the code so that the
code for a bus is only called if the bus is being built.
When SPI support was added to serial-multi-instantiate it created a
dependency that both CONFIG_I2C and CONFIG_SPI must be enabled.
Typically they are, but there's no reason why this should be a
requirement. A specific kernel build could have only I2C devices
or only SPI devices. It should be possible to use serial-multi-instantiate
if only I2C or only SPI is enabled.
The dependency formula used is:
depends on (I2C && !SPI) || (!I2C && SPI) || (I2C && SPI)
The advantage of this approach is that if I2C=m or SPI=m then
SERIAL_MULTI_INSTANTIATE is limited to n/m.

The LEGX0820 ACPI device is expected to provide a custom operation
region:
OperationRegion (XIN1, 0x8F, Zero, 0x04B0)
Field (XIN1, AnyAcc, Lock, Preserve)
{
DMSG, 8,
HDAP, 8,
Offset (0x03),
AFNM, 8,
Offset (0x10),
P80B, 8,
P81B, 8,

P83B, 8,
P84B, 8,

P86B, 8,

TMP1, 8,
LTP1, 8,
HTP1, 8,
TMP2, 8,
LTP2, 8,
HTP2, 8,
Offset (0x3E8),
PMSG, 1600
}
The PMSG field is used by AML code to log debug messages when DMSG is
true. Since those debug messages are already logged using the standard
ACPI Debug object, we set DMSG unconditionally to 0x00 and ignore any
writes to PMSG.
The TMPx, LTPx, HTPx and AFNM fields are used to inform the driver when
the temperature/(presumably) trip points/fan mode changes. This only
happens when the DTTM flag is set.
Unfortunately we have to implement support for this operation region
because the AML codes uses code constructs like this one:
If (((\_SB.XINI.PLAV != Zero) && (\_SB.XINI.DTTM != Zero)))
The PLAV field gets set to 1 when the driver registers its address space
handler, so by default XIN1 should not be accessed.
However ACPI does not use short-circuit evaluation when evaluating
logical conditions. This causes the DTTM field to be accessed even
when PLAV is 0, which results in an ACPI error.
Since this check happens inside various thermal-related ACPI control
methods, various thermal zone become unusable since any attempt to
read their temperature results in an ACPI error.
Fix this by providing support for this operation region. I suspect
that the problem does not happen under Windows (which seemingly does
not use short-circuit evaluation either) because the necessary driver
comes preinstalled with the machine.

There is a small window in ssam_serial_hub_probe() where the controller
is initialized but has not been started yet. Specifically, between
ssam_controller_init() and ssam_controller_start(). Any failure in this
window, for example caused by a failure of serdev_device_open(),
currently results in an incorrect warning being emitted.
In particular, any failure in this window results in the controller
being destroyed via ssam_controller_destroy(). This function checks the
state of the controller and, in an attempt to validate that the
controller has been cleanly shut down before we try and deallocate any
resources, emits a warning if that state is not SSAM_CONTROLLER_STOPPED.
However, since we have only just initialized the controller and have not
yet started it, its state is SSAM_CONTROLLER_INITIALIZED. Note that this
is the only point at which the controller has this state, as it will
change after we start the controller with ssam_controller_start() and
never revert back. Further, at this point no communication has taken
place and the sender and receiver threads have not been started yet (and
we may not even have an open serdev device either).
Therefore, it is perfectly safe to call ssam_controller_destroy() with a
state of SSAM_CONTROLLER_INITIALIZED. This, however, means that the
warning currently being emitted is incorrect. Fix it by extending the
check.

Add tracing support for the SBAF IFS tests, which may be useful for
debugging systems that fail these tests. Log details like test content
batch number, SBAF bundle ID, program index and the exact errors or

In a core, the SBAF test engine is shared between sibling CPUs.
An SBAF test image contains multiple bundles. Each bundle is further
composed of subunits called programs. When a SBAF test (for a particular
core) is triggered by the user, each SBAF bundle from the loaded test
image is executed sequentially on all the threads on the core using
the stop_core_cpuslocked mechanism. Each bundle execution is initiated by
writing to MSR_ACTIVATE_SBAF.
SBAF test bundle execution may be aborted when an interrupt occurs or
if the CPU does not have enough power budget for the test. In these
cases the kernel restarts the test from the aborted bundle. SBAF
execution is not retried if the test fails or if the test makes no
forward progress after 5 retries.

Structural Based Functional Test at Field (SBAF) is a new type of
testing that provides comprehensive core test coverage complementing
existing IFS tests like Scan at Field (SAF) or ArrayBist.
SBAF device will appear as a new device instance (intel_ifs_2) under
/sys/devices/virtual/misc. The user interaction necessary to load the
test image and test a particular core is the same as the existing scan
test (intel_ifs_0).
During the loading stage, the driver will look for a file named
ff-mm-ss-<batch02x>.sbft in the /lib/firmware/intel/ifs_2 directory.
The hardware interaction needed for loading the image is similar to
SAF, with the only difference being the MSR addresses used. Reuse the
SAF image loading code, passing the SBAF-specific MSR addresses via
struct ifs_test_msrs in the driver device data.
Unlike SAF, the SBAF test image chunks are further divided into smaller
logical entities called bundles. Since the SBAF test is initiated per
bundle, cache the maximum number of bundles in the current image, which
is used for iterating through bundles during SBAF test execution.

IFS tests such as Scan at Field (SAF) or Structural Based Functional
Test at Field (SBAF), require the user to load a test image. The image
loading process is similar across these tests, with the only difference
being MSR addresses used. To reuse the code between these tests, remove
the hard coding of MSR addresses and allow the driver to pass the MSR
addresses per IFS test (via driver device data).
Add a new structure named "struct ifs_test_msrs" to specify the
test-specific MSR addresses. Each IFS test will provide this structure,
enabling them to reuse the common code.
This is a preliminary patch in preparation for the addition of SBAF
support.

simplified. Since these functions are only called during module_init()

misc_register()/misc_deregister or isst_if_cpu_info_init()/
isst_if_cpu_info_exit().

When rebinding the driver, it also ends up touching freed memory when

If the Ambient Light Sensor (ALS) is disabled, the current code in the PMF
driver does not query for Human Presence Detection (HPD) data in
amd_pmf_get_sensor_info(). As a result, stale HPD data is used by PMF-TA
to evaluate policy conditions, leading to unexpected behavior in the policy
output actions.
To resolve this issue, modify the PMF driver to query HPD data
independently of ALS.
Since user_present is a boolean, modify the current code to return true if
the user is present and false if the user is away or if the sensor is not
detected, and report this status to the PMF TA firmware accordingly.
With this change, amd_pmf_get_sensor_info() now returns void instead of
int.

On almost all ASUS ROG series laptops the MCU used for the USB keyboard
also has a HID packet used for setting the brightness. This is usually
the same as the WMI method. But in some laptops the WMI method either
is missing or doesn't work, so we should default to the HID control.

Since commit e2ffcda162 ("ACPI: OSL: Allow Notify () handlers to run on
all CPUs") ACPI notify handlers like the intel-vbtn notify_handler() may
run on multiple CPU cores racing with themselves.
This race gets hit on Dell Venue 7140 tablets when undocking from
the keyboard, causing the handler to try and register priv->switches_dev
twice, as can be seen from the dev_info() message getting logged twice:

The cros_ec_get_host_command_version_mask() function requires that the
caller must have ec_dev->lock mutex before calling it. This requirement
was not met and as a result it was possible that two commands were sent
to the device at the same time.
The problem was observed while using UART backend which doesn't use any
additional locks, unlike SPI backend which locks the controller until
response is received.

This just standardizes the use of MIN() and MAX() macros, with the very
traditional semantics. The goal is to use these for C constant
expressions and for top-level / static initializers, and so be able to
simplify the min()/max() macros.
These macro names were used by various kernel code - they are very
traditional, after all - and all such users have been fixed up, with a
few different approaches:
- trivial duplicated macro definitions have been removed
Note that 'trivial' here means that it's obviously kernel code that
already included all the major kernel headers, and thus gets the new
generic MIN/MAX macros automatically.
- non-trivial duplicated macro definitions are guarded with #ifndef
This is the "yes, they define their own versions, but no, the include
situation is not entirely obvious, and maybe they don't get the
generic version automatically" case.
- strange use case #1
A couple of drivers decided that the way they want to describe their
versioning is with
#define MAJ 1
#define MIN 2
#define DRV_VERSION __stringify(MAJ) "." __stringify(MIN)
which adds zero value and I just did my Alexander the Great
impersonation, and rewrote that pointless Gordian knot as
#define DRV_VERSION "1.2"
instead.
- strange use case #2
A couple of drivers thought that it's a good idea to have a random
'MIN' or 'MAX' define for a value or index into a table, rather than
the traditional macro that takes arguments.
These values were re-written as C enum's instead. The new
function-line macros only expand when followed by an open
parenthesis, and thus don't clash with enum use.
Happily, there weren't really all that many of these cases, and a lot of
users already had the pattern of using '#ifndef' guarding (or in one
case just using '#undef MIN') before defining their own private version
that does the same thing. I left such cases alone.

Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
samsung, imx, zynq and amlogic platoforms are farily small maintenance
changes, either addressing minor mistakes or enabling additional hardware.
The qualcomm platform changes add a number of features and are larger
than the other ones combined, introducing the use of linux/cleanup.h
across several drivers, adding support for Snapdragon X1E and other
SoCs in platform drivers, a new "protection domain mapper" driver, and a
"shared memory bridge" driver.
The cznic "turris omnia" router based on Marvell Armada gets a platform
driver that talks to the board specific microcontroller.
The reset and cache subsystems get a few minor updates to SoC specific
drivers, while the ff-a, scmi and optee firmware drivers get some
code refactoring and new features.

Smatch complains that 'str' can be used without being initialized:
drivers/platform/x86/intel/intel_plr_tpmi.c:178 plr_print_bits()
error: uninitialized symbol 'str'.
In this loop, we iterate over all the set bits and print the name of the
bit. The intention is that if there is a bit which is between 0-31 we
look for the name in the first array plr_coarse_reasons[] which has 10
elements. If the bit is in the 32-63 range we look for it in the
plr_fine_reasons[] array which has 30 elements. If the bit is in the
invalid ranges, 10-31 or 62-63, then we should print "UNKNOWN(%d)".
The problem is that 'str' needs to be initialized at the start of each
iteration, otherwise if we can't find the string then instead of printing
"UNKNOWN(%d)", we will re-print whatever the previous bit was.

Fix a platform profile option switch/getter bug on some Omen and Victus
laptops dismissing userspace choice when selecting performance mode in
inadequate conditions (e.g. by being disconnected from the AC power plug)
by
- hooking an ACPI notify handler through the
omen_register_powersource_event_handler method that listens to AC
power source changes (plugging in/out the AC power plug)
- keeping an intermediate active_platform_profile variable that is
set when userspace changes the platform profile setting
- restoring the selected platform profile kept in
active_platform_profile when AC power is plugged back into the
laptop through the power_supply_is_system_supplied call check,
unless if the user decided to alter the platform profile mid-way
Add a dependency to the POWER_SUPPLY subsystem to be able to check for
power_supply_is_system_supplied.
Introduce intermediary functions to leverage platform profile <->
internal thermal profile translation code from platform_profile_omen_set
and callers.
These changes makes the module compliant with the principles defined in
the Platform Profile Selection page of the Kernel documentation on those
kind of laptops; which is to not "(...) let userspace know about any
sub-optimal conditions which are impeding reaching the requested
performance level".
Since the Omen and Victus laptops share the same embedded controller
system, the fix is applicable to both categories of laptops.

In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *. This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.
Because the match() callback is in all busses, all busses are modified
to handle this properly. This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.
For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

The global hci_hotkey_quickstart quirk flag is tested in
toshiba_acpi_enable_hotkeys() before the quirk flag is properly
initialized based on SMBIOS data. This causes the quirk to be
applied to all models, some of which behave erratically as a
result.
Fix this by initializing the global quirk flags during module
initialization before registering the ACPI driver. This also
allows us to mark toshiba_dmi_quirks[] as __initconst.

When reading token data from sysfs on my Inspiron 3505, the token
locations and values are wrong. This happens because match_attribute()
blindly assumes that all entries in da_tokens have an associated
entry in token_attrs.
This however is not true as soon as da_tokens[] contains zeroed
token entries. Those entries are being skipped when initialising
token_attrs, breaking the core assumption of match_attribute().
Fix this by defining an extra struct for each pair of token attributes
and use container_of() to retrieve token information.

Each TPMI power domain includes a group of CPUs. Several power
management settings in this case applicable to a group of CPUs.
There can be several power domains in a CPU package. So, provide
interfaces for:
- Get power domain id for a Linux CPU
- Get mask of Linux CPUs in a power domain
Hardware Punit uses different CPU numbering, which is not based on
APIC (Advanced Programmable Interrupt Controller) CPU numbering.
The Linux CPU numbering is based on APIC CPU numbering. Some PM features
like Intel Speed Select, the CPU core mask provided by the hardware is
based on the Punit CPU numbering. To use the core mask, this mask
needs to be converted to a Linux CPUs mask. So, provide interfaces for:
- Convert to a Linux CPU number from a Punit CPU number
- Convert to a Punit CPU number from a Linux CPU number
On each CPU online, MSR 0x54 is used to read the mapping and stores in
a per cpu array. Create a hash for faster searching of a Linux CPU number
from a Punit CPU number.

SST common module is loaded when model specific or TPMI SST driver
registers for services. There are model specific features used in SST
common modules which are checked with a CPU model list. So, this module
is model specific.
There are some use cases where loading the common module independently
only on the supported CPU models helps. The first use case is for
preventing SST TPMI module loading if the model specific features are
not implemented. The second use case for presenting information to
user space when SST is used in OOB (Out of Band) mode.
1.
With TPMI, SST interface is architectural. This means that no need to add
new PCI device IDs for new CPU models. This means that there can be lag
in adding CPU models for the model specific features in the common
module. For example, before adding CPU model to GRANITERAPIDS_D to
hpm_cpu_ids[], SST is still functional for some features and but will
get/set wrong data for features like SST-CP. This is because IOCTL
ISST_IF_GET_PHY_ID, will not give correct mapping for newer CPU models.
So adding explicit model check during load time will prevent such cases.
For unsupported CPU models, common driver will fail to load and hence
dependent modules will not be loaded.
2.
When the SST TPMI features are controlled by some OOB agent (not from OS
interface), even if the CPU model is supported, there will be no user
space interface available for tools as SST TPMI modules will not
be loaded. User space interface is registered when TPMI modules call
isst_if_cdev_register(). Even in this case user space orchestrator
software needs to get power domain information to schedule workload and
get/set turbo ratio limits. This information is exposed by the common
module using IOCTLs ISST_IF_GET_PHY_ID and ISST_IF_MSR_COMMAND
respectively. Since the user space MSR access can be locked, direct MSR
access from the user space is not an option using /dev/cpu/*/msr.
Converge all the existing model checks to one common place and
use driver data to differentiate. On successful model check
call isst_misc_reg().

On x86/ACPI platforms touchscreens mostly just work without needing any
device/model specific configuration. But in some cases (mostly with Silead
and Goodix touchscreens) it is still necessary to manually specify various
touchscreen-properties on a per model basis.
touchscreen_dmi is a special place for DMI quirks for this, but it can be
challenging for users to figure out the right property values, especially
for Silead touchscreens where non of these can be read back from
the touchscreen-controller.
ATM users can only test touchscreen properties by editing touchscreen_dmi.c
and then building a completely new kernel which makes it unnecessary
difficult for users to test and submit properties when necessary for their
laptop / tablet model.
Add support for specifying properties on the kernel commandline to allow
users to easily figure out the right settings. See the added documentation
in kernel-parameters.txt for the commandline syntax.

After commit 2fbe479c00 ("platform/chrome: cros_ec: Handle events
during suspend after resume completion"), cros_ec_resume() starts to
call cros_ec_resume_early() and cros_ec_resume_complete().
To be neat, let cros_ec_suspend() call cros_ec_suspend_prepare() and
cros_ec_suspend_late().

Here is the small set of driver core and kernfs changes for 6.10-rc1.
Nothing major here at all, just a small set of changes for some driver
core apis, and minor fixups. Included in here are:
- sysfs_bin_attr_simple_read() helper added and used
- device_show_string() helper added and used
All usages of these were acked by the various maintainers. Also in here
are:
- kernfs minor cleanup
- removed unused functions
- typo fix in documentation
- pay attention to sysfs_create_link() failures in module.c finally.
All of these have been in linux-next for a very long time with no
reported problems.

These make the ACPI EC driver always install the EC address space handler
at the root of the ACPI namespace which causes it to take care of all EC
operation regions everywhere, so in particular the custom EC address
space handler in the WMI driver is not needed any more and accordingly
it gets removed altogether.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Skip E820 checks for MCFG ECAM regions for new (2016+) machines,

platforms require ECAM to work (Bjorn Helgaas)
- Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien
Le Moal)
- Remove last user and pci_enable_device_io() (Heiner Kallweit)
- Wait for Link Training==0 to avoid possible race (Ilpo Järvinen)
- Skip waiting for devices that have been disconnected while
suspended (Ilpo Järvinen)

and Unsupported Request errors are an expected part of enumeration
(Vidya Sagar)
MSI:
- Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas)
Error handling:
- Mask Genesys GL975x SD host controller Replay Timer Timeout
correctable errors caused by a hardware defect; the errors cause
interrupts that prevent system suspend (Kai-Heng Feng)

but assumed revision 6 behavior (Kuppuswamy Sathyanarayanan)
ASPM:
- Simplify link state definitions and mask calculation (Ilpo
Järvinen)
Power management:
- Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS
apparently doesn't know how to put them back in D0 (Mario
Limonciello)
CXL:
- Support resetting CXL devices; special handling required because
CXL Ports mask Secondary Bus Reset by default (Dave Jiang)
DOE:
- Support DOE Discovery Version 2 (Alexey Kardashevskiy)
Endpoint framework:
- Set endpoint BAR to be 64-bit if the driver says that's all the
device supports, in addition to doing so if the size is >2GB
(Niklas Cassel)
- Simplify endpoint BAR allocation and setting interfaces (Niklas
Cassel)
Cadence PCIe controller driver:
- Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof
Kozlowski)

NVIDIA Tegra194 PCIe controller driver:
- Return success for endpoint probe instead of falling through to the
failure path (Vidya Sagar)

BAR value (Niklas Cassel)
- Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski)
- Set the Subsystem Vendor ID, which was previously zero because it
was masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
up things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
to dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)
- Add DT binding J722S SoC support (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Add DT binding missing num-viewport, phys and phy-name properties
(Jan Kiszka)
Miscellaneous:

The custom EC address space handler in the WMI driver was only needed
because the EC driver did not install its address space handler for
EC operation regions beyond the EC device scope in the ACPI namespace.
That has just changed, so the custom EC address handler is not needed
any more and it can be removed.

Some MeeGoPad top-set boxes have an ANX7428 Type-C Switch for USB3.1 Gen 1
and DisplayPort over Type-C alternate mode support.
The ANX7428 has a microcontroller which takes care of the PD negotiation
and automatically sets the builtin Crosspoint Switch to send the right
signal to the 4 highspeed pairs of the Type-C connector. It also takes
care of HPD and AUX channel routing for DP alternate mode.
IOW the ANX7428 operates fully autonomous and to the x5-Z8350 SoC
things look like there simple is a USB-3 Type-A connector and a
separate DisplayPort connector. Except that the BIOS does not
power on the ANX7428 at boot (meh).
Add a driver to power on the ANX7428. This driver is added under
drivers/platform/x86 rather than under drivers/usb/typec for 2 reasons:
1. This driver is specifically written to work with how the ANX7428 is
described in the ACPI tables of the MeeGoPad x86 (Cherry Trail) devices.
2. This driver only powers on the ANX7428 and does not do anything wrt
its Type-C functionality. It should be possible to tell the controller
which data- and/or power-role to negotiate and to swap the role(s) after
negotiation but the MeeGoPad top-set boxes always draw their power from
a separate power-connector and they only support USB host-mode. So this
functionality is unnecessary and due to lack of documentation this is
tricky to support.

Dell All In One (AIO) models released after 2017 use a backlight controller
board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Instead of having a separate ACPI device with an UartSerialBusV2() resource
to model the backlight-controller, which would be the standard way to do
this.
The acpi_quirk_skip_serdev_enumeration() has special handling for this
and it will make the serial port code create a serdev controller device
for the UART instead of a /dev/ttyS0 char-dev. It will also create
a dell-uart-backlight driver platform device for this driver to bind too.
This new kernel module contains 2 drivers for this:
1. A simple platform driver which creates the actual serdev device
(with the serdev controller device as parent)
2. A serdev driver for the created serdev device which exports
the backlight functionality uses a standard backlight class device.

The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons
on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED
controller which is controlled by the "pwm_soc_lpss_2" PWM output.
Create a LED class device for this, using the new input-events trigger
as default trigger so that the buttons automatically light up on any
input activity.
Note alternatively a "leds_pwm" platform device could be created together
with the necessary fwnode_s_ and a fwnode link to the PWM controller.
There are 2 downsides to this approach:
1. The code would still need to pwm_get() the PWM controller to get/attach
a fwnode for the PWM controller fwnode link and setting up the necessary
fwnodes is non-trivial. So this would likely require more code then simply
registering the LED class device directly.
2. Currently the leds_pwm driver and its devicetree bindings do not support
limiting the maximum dutycycle to less then 100% which is required in this
case (the leds_pwm driver can probably be extended to allow this).

3. Put the fwnode link for red before green in ktd2026_node_group[] so that

up until pcibios_assign_resources(), which is an fs_initcall().
- Move p2sb_fs_init() to an fs_initcall_sync(). This is still early
enough to avoid a race with any dependent drivers.

Commit 47ea0ddb1f ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable") re-ordered the resume sequence. Before that
change, cros_ec resume sequence is:
1) Enable IRQ
2) Send resume event
3) Handle events during suspend
After commit 47ea0ddb1f ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable"), cros_ec resume sequence is:
1) Enable IRQ
2) Handle events during suspend
3) Send resume event.
This re-ordering leads to delayed handling of any events queued between
items 2) and 3) with the updated sequence. Also in certain platforms, EC
skips triggering interrupt for certain events eg. mkbp events until the
resume event is received. Such events are stuck in the host event queue
indefinitely. This change puts back the original order to avoid any
delay in handling the pending events.

A partitioned system has two different PCI VSEC devices per package.
A non-partitioned device has only one PCI VSEC device per package.
The current implementation only supports non partitioned systems.
Each partition maps a set of power domains. Other than reading from
different MMIO regions, there is no change in the SST functionality.
The scope of SST control is still per power domain. Hence user space
does not need to be aware of existence of partitions.
With partitions, existing per package information defined using struct
tpmi_sst_struct is enhanced to store information for both partitions. A
mapping function map_partition_power_domain_id() is introduced, which
maps to correct partition and index. This mapping function is called
in get_instance() and isst_if_clos_assoc(), before indexing into
tpmi_sst_struct->power_domain_info[].
The TPMI core platform info provides partition id and compute die ID
mask for each partition. Use this information to order power domains,
so that compute dies are presented before IO dies to match hardware
defined compute die ID for each CPU.

The driver was reverse-engineered based on a user request to the

The ACPI WMI interface used by this driver seems to use the same
embedded controller interface as the msi-ec driver, but supports
automatic discovery of supported machines without relying on a
DMI whitelist.

The X1 carbon 2014 / 2nd gen's adaptive keyboard top row's "Home" mode,
which is 1 of the 2 modes Linux supports, has clipping-tool and cloud
buttons which so far are not mapped.
I assume these were left as KEY_RESERVED because no suitable KEY_FOO codes
were available when support was added.
In the mean time we have gotten KEY_SELECTIVE_SCREENSHOT and this has been
used for the clipping-tool function under Fn + PrtSc on more traditional
ThinkPad keyboards already.
Finding a KEY_FOO code for the cloud key is harder looking at the symbol
it seems to refer to cloud-storage which made me think of file syncing,
or file transfer which has let me to pick KEY_XFER for this.
Note this is based on looking at a picture of the adaptive top row
in Home mode and has not been tested on an actual adaptive keyboard.

Switch the hotkey keymap handling over to the sparse-keymap helpers,
there should be no functional changes from this.
Note all the mappings to KEY_UNKNOWN are removed since that is the default
behavior of sparse_keymap_report_event() for unknown scancodes.
Also drop the big comment about making changes to the keymaps since

The input core already filters out EV_KEY events for KEY_RESERVED,
remove the check for this in tpacpi_input_send_key() and rely
on the input core filtering instead.
Also change tpacpi_input_send_key() to only report the scancode
once instead of reporting it on both press and release. Together
these 2 changes make tpacpi_input_send_key() behave the same as
sparse_keymap_report_event().
The goal of this patch is to have a separate commit with
the slightly different behavior from sparse_keymap_report_event()
before switching over to using the sparse-keymap helpers.

Change the default keymap to report the correct keycodes for the volume and
brightness keys. Reporting key events for these is already filtered out by
the hotkey_reserved_mask which masks these keys out of hotkey_user_mask at
initialization time, so there is no need to also map them to KEY_RESERVED.
This avoids users, who want these to be reported, having to also remap
the keycodes on top of overriding hotkey_user_mask to report these
and Linux userspace has already been overriding the KEY_RESERVED mappings
with the correct keycodes through udev/hwdb/60-keyboard.hwdb for years now.
Also drop hotkey_unmap() it was only used to dynamically map the brightness
keys to KEY_RESERVED and after removing that it has no remaining users.

Change the hotkey_reserved_mask initialization to hardcode the list
of reserved keys. There are only a few reserved keys and the code to
iterate over the keymap will be removed when moving to sparse-keymaps.
Note only the 32 original hotkeys are affected by the hotkey_*_mask values:
if (i < sizeof(hotkey_reserved_mask)*8)
hotkey_reserved_mask |= 1 << i;
The (i < sizeof(hotkey_reserved_mask)*8) condition translates to (i < 32)
so this code only ever set bits in hotkey_reserved_mask for the 32 original
hotkeys. Therefor this patch does not set any bits in hotkey_reserved_mask
for the KEY_RESERVED mappings for the adaptive keyboard scancodes.

Do not send ACPI netlink events for unknown hotkeys, to avoid userspace
starting to rely on them. Instead these should be added to the keymap to
send evdev events.
This should not cause a behavior change for existing laptop models since
all currently known 0x1xxx events have a mapping.
In hindsight the ACPI netlink events should have been suppressed for
the adaptive keyboard and extended hotkeys events too. But the kernel has
been sending ACPI netlink events for those for a long time now, so we
cannot just stop sending them without potentially causing issues for
existing users who may depend on these.

For the original hotkey codes 0x1001 - 0x1020 tpacpi_driver_event() never

never happens when called from tpacpi_hotkey_send_key() so behavior does

Driver issues a WRMSR(MSR_AUTHENTICATE_AND_COPY_CHUNK) operation to do
this. This operation can take up to 5 msec, and if an interrupt occurs
in between, the AUTH_AND_COPY_CHUNK u-code implementation aborts the

Interrupt sources such as NMI or SMI are handled by retrying. Regular

completing. Disable irq on local cpu around the aforementioned WRMSR to

lpc_driver_data stores the MMIO port base for EC mapped memory.
cros_ec_lpc_readmem uses this port base instead of hardcoding
EC_LPC_ADDR_MEMMAP.

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them.

Use the `DEFINE_RAW_FLEX()` helper for an on-stack definition of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.
So, with these changes, fix the following warning:

BIOS 03.05 still hasn't fixed the spurious IRQ1 issue. As it's still
being worked on there is still a possibility that it won't need to
apply to future BIOS releases.
Add a quirk for BIOS 03.05 as well.

ROG Zephyrus G14 advertises support for SPS notifications to the
BIOS but doesn't actually use them. Instead the asus-nb-wmi driver
utilizes such events.
Add a quirk to prevent the system from registering for ACPI platform
profile when this system is found to avoid conflicts.
