ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

9958d30f38 media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

e941dc13fd Input: zinitix - do not report shadow fingers
I observed the following problem with the BT404 touch pad
running the Phosh UI:

When e.g. typing on the virtual keyboard pressing "g" would
produce "ggg".

After some analysis it turns out the firmware reports that three
fingers hit that coordinate at the same time, finger 0, 2 and
4 (of the five available 0,1,2,3,4).

DOWN
  Zinitix-TS 3-0020: finger 0 down (246, 395)
  Zinitix-TS 3-0020: finger 1 up (0, 0)
  Zinitix-TS 3-0020: finger 2 down (246, 395)
  Zinitix-TS 3-0020: finger 3 up (0, 0)
  Zinitix-TS 3-0020: finger 4 down (246, 395)
UP
  Zinitix-TS 3-0020: finger 0 up (246, 395)
  Zinitix-TS 3-0020: finger 2 up (246, 395)
  Zinitix-TS 3-0020: finger 4 up (246, 395)

This is one touch and release: i.e. this is all reported on
touch (down) and release.

There is a field in the struct touch_event called finger_cnt
which is actually a bitmask of the fingers active in the
event.

Rename this field finger_mask as this matches the use contents
better, then use for_each_set_bit() to iterate over just the
fingers that are actally active.

Factor out a finger reporting function zinitix_report_fingers()
to handle all fingers.

Also be more careful in reporting finger down/up: we were
reporting every event with input_mt_report_slot_state(..., true);
but this should only be reported on finger down or move,
not on finger up, so also add code to check p->sub_status
to see what is happening and report correctly.

After this my Zinitix BT404 touchscreen report fingers
flawlessly.

The vendor drive I have notably does not use the "finger_cnt"
and contains obviously incorrect code like this:

  if (touch_dev->touch_info.finger_cnt > MAX_SUPPORTED_FINGER_NUM)
      touch_dev->touch_info.finger_cnt = MAX_SUPPORTED_FINGER_NUM;

As MAX_SUPPORTED_FINGER_NUM is an ordinal and the field is
a bitmask this seems quite confused.

04b7762e37 Input: elan_i2c - fix regulator enable count imbalance after suspend/resume
Before these changes elan_suspend() would only disable the regulator
when device_may_wakeup() returns false; whereas elan_resume() would
unconditionally enable it, leading to an enable count imbalance when
device_may_wakeup() returns true.

This triggers the "WARN_ON(regulator->enable_count)" in regulator_put()
when the elan_i2c driver gets unbound, this happens e.g. with the
hot-plugable dock with Elan I2C touchpad for the Asus TF103C 2-in-1.

Fix this by making the regulator_enable() call also be conditional
on device_may_wakeup() returning false.

elan_disable_power() is called conditionally on suspend, where as
elan_enable_power() is always called on resume. This leads to
an imbalance in the regulator's enable count.

Move the regulator_[en|dis]able() calls out of elan_[en|dis]able_power()
in preparation of fixing this.

No functional changes intended.

ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular
GPIO ACPI resource in their ACPI tables.

Some CHT devices have a bug, where the also is bogus interrupt resource
(likely copied from a previous Bay Trail based generation of the device).

The i2c-core-acpi code will assign the bogus, non-working, interrupt
resource to client->irq. Add a workaround to fix this up.

7b1f781f2d Input: psmouse - set up dependency between PS/2 and SMBus companions
When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

37ef4c19b4 Input: clear BTN_RIGHT/MIDDLE on buttonpads
Buttonpads are expected to map the INPUT_PROP_BUTTONPAD property bit
and the BTN_LEFT key bit.

As explained in the specification, where a device has a button type
value of 0 (click-pad) or 1 (pressure-pad) there should not be
discrete buttons:
https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/touchpad-windows-precision-touchpad-collection#device-capabilities-feature-report

However, some drivers map the BTN_RIGHT and/or BTN_MIDDLE key bits even
though the device is a buttonpad and therefore does not have those
buttons.

This behavior has forced userspace applications like libinput to
implement different workarounds and quirks to detect buttonpads and
offer to the user the right set of features and configuration options.
For more information:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/726

In order to avoid this issue clear the BTN_RIGHT and BTN_MIDDLE key
bits when the input device is register if the INPUT_PROP_BUTTONPAD
property bit is set.

Notice that this change will not affect udev because it does not check
for buttons. See systemd/src/udev/udev-builtin-input_id.c.

The supply names of the Zinitix touchscreen were a bit confused, the new
bindings rectifies this.

To deal with old and new devicetrees, first check if we have "vddo" and in
case that exists assume the old supply names. Else go and look for the new
ones.

We cannot just get the regulators since we would get an OK and a dummy
regulator: we need to check explicitly for the old supply name.

Use struct device *dev as a local variable instead of the I2C client since
the device is what we are actually obtaining the resources from.

Since irq request is the last thing in the driver probe, it happens
later than the input device registration. This means that there is a
small time window where if the open method is called the driver will
attempt to enable not yet available irq.

Fix that by moving the irq request before the input device registration.

Hans de Goede
8a78050ee2 Input: axp20x-pek - revert "always register interrupt handlers" change
The power button on Cherry Trail systems with an AXP288 PMIC is connected
to both the power button pin of the PMIC as well as to a power button GPIO
on the Cherry Trail SoC itself. This leads to double power button event
reporting which is a problem.

Since reporting power button presses through the PMIC is not supported on
all PMICs used on Cherry Trail systems, we want to keep the GPIO
power button events, so the axp20x-pek code checks for the presence of
a GPIO power button and in that case does not register its input-device.

On most systems the GPIO power button also can wake-up the system from
suspend, so the axp20x-pek driver would also not register its interrupt
handler. But on some systems there was a bug causing wakeup by the GPIO
power button handler to not work.

Commit 9747070c11d6 ("Input: axp20x-pek - always register interrupt
handlers") was added as a work around for this registering the axp20x-pek
interrupts, but not the input-device on Cherry Trail systems.

In the mean time the root-cause of the GPIO power button wakeup events
not working has been found and fixed by the "pinctrl: cherryview: Do not
allow the same interrupt line to be used by 2 pins" patch,
so this is no longer necessary.

This reverts the workaround going back to only registering the
interrupt handlers on systems where we also register the input-device.

In fact, axis data in Spaceball movement reports are signed 16-bit

visually inspecting the data packets, and later verified by consulting:

Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.

This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.

So this patch moves dev->work initialization before registering input
device

66d27d848f Input: silead - add support for EFI-embedded fw using different min/max coordinates
Unfortunately, at the time of writing this commit message, we have been
unable to get permission from Silead, or from device OEMs, to distribute
the necessary Silead firmware files in linux-firmware.

On a whole bunch of devices the UEFI BIOS code contains a touchscreen
driver, which contains an embedded copy of the firmware. The fw-loader
code has a "platform" fallback mechanism, which together with info on the
firmware from drivers/platform/x86/touchscreen_dmi.c will use the firmware
from the UEFI driver when the firmware is missing from /lib/firmware. This
makes the touchscreen work OOTB without users needing to manually download
the firmware.

The firmware bundled with the original Windows/Android is usually newer
then the firmware in the UEFI driver and it is better calibrated. This
better calibration can lead to significant differences in the reported
min/max coordinates.

Add support for a new (optional) "silead,efi-fw-min-max" property which
provides a set of alternative min/max values to use for the x/y axis when
the EFI embedded firmware is used.

The new property is only used on (x86) devices which do not use devicetree,
IOW it is not used in actual devicetree files. The devicetree-bindings
maintainers have requested properties like these to not be added to the
devicetree-bindings, so the new property is deliberately not added to the
existing silead devicetree-bindings documentation.

goodix_get_gpio_config() errors are fatal (abort probe()) so log them
at KERN_ERR level rather then as debug messages.

The "id_buf" buffer is stored in "data->raw_info_block" and freed by
"mxt_free_object_table" in case of error.

Return instead of jumping to avoid a double free.

5ede7f0cfb Input: goodix - add pen support
Some Goodix touchscreens have support for a (Goodix) active pen, add
support for this. The info on how to detect when a pen is down and to
detect when the stylus buttons are pressed was lifted from the out
of tree Goodix driver with pen support written by Adya:
https://gitlab.com/AdyaAdya/goodix-touchscreen-linux-driver/

Since there is no way to tell if pen support is present, the registering
of the pen input_dev is delayed till the first pen event is detected.

This has been tested on a Trekstor Surftab duo W1, a Chuwi Hi13 and
a Cyberbook T116 tablet.

8c374ef454 Input: ff-core - correct magnitude setting for rumble compatibility
When converting a rumble into a periodic effect, for compatibility,
the magnitude is effectively calculated using:

magnitude = max(strong_rubble / 3 + weak_rubble / 6, 0x7fff);

The rumble magnitudes are both u16 and the resulting magnitude is
s16. The max is presumably an attempt to limit the result of the
calculation to the maximum possible magnitude for the s16 result,
and thus should be a min.

However in the case of strong = weak = 0xffff, the result of the first
part of the calculation is 0x7fff, meaning that the min would be
redundant anyway, so simply remove the current max.

a2fd46cd3d Input: goodix - try not to touch the reset-pin on x86/ACPI devices
Unless the controller is not responding at boot or after suspend/resume,
the driver never resets the controller on x86/ACPI platforms. The driver
still requesting the reset pin at probe() though in case it needs it.

Until now the driver has always requested the reset pin with GPIOD_IN
as type. The idea being to put the pin in high-impedance mode to save
power until the driver actually wants to issue a reset.

But this means that just requesting the pin can cause issues, since
requesting it in another mode then GPIOD_ASIS may cause the pinctrl
driver to touch the pin settings. We have already had issues before
due to a bug in the pinctrl-cherryview.c driver which has been fixed in
commit 921daeeca91b ("pinctrl: cherryview: Preserve
CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs").

And now it turns out that requesting the reset-pin as GPIOD_IN also stops
the touchscreen from working on the GPD P2 max mini-laptop. The behavior
of putting the pin in high-impedance mode relies on there being some
external pull-up to keep it high and there seems to be no pull-up on the
GPD P2 max, causing things to break.

This commit fixes this by requesting the reset pin as is when using
the x86/ACPI code paths to lookup the GPIOs; and by not dropping it
back into input-mode in case the driver does end up issuing a reset
for error-recovery.
