Roger Quadros (TI) added support for dual-role using the OTG block
available in some dwc3 implementations, this makes sure that AM437x

We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
the work of Martin Blumenstingl.
We also have a ton of changes in dwc2 (51% of all changes, in
fact). The most interesting part there is the support for
Hibernation (a Synopsys PM feature).

Some UDC may want to allocate endpoints dynamically, either because
the HW supports an arbitrary large number or because (like the Aspeed
BMC SoCs), the pool of HW endpoints is shared between multiple gadgets.
The allocation side can be done rather easily using the existing
match_ep() UDC hook.
However we have no good place to "free" them.
This implements a "simple" variant of this, which calls an EP dispose
callback on all EPs associated with a gadget when the composite device
gets unbound.
This is required by my upcoming Aspeed vHub driver.

The AXP288 BC1.2 charger detection / extcon code may seem like a strange
place to add code to control the USB role-switch on devices with an AXP288,
but there are 2 reasons to do this inside the axp288 extcon code:
1) On many devices the USB role is controlled by ACPI AML code, but the AML
code only switches between the host and none roles, because of Windows
not really using device mode. To make device mode work we need to toggle
between the none/device roles based on Vbus presence, and the axp288
extcon gets interrupts on Vbus insertion / removal.
2) In order for our BC1.2 charger detection to work properly the role
mux must be properly set to device mode before we do the detection.
Also note the Kconfig help-text / obsolete depends on USB_PHY which are
remnants from older never upstreamed code also controlling the mux from
the axp288 extcon code.
This commit also adds code to get notifications from the INT3496 extcon
device, which is used on some devices to notify the kernel about id-pin
changes instead of them being handled through AML code.
This fixes:
-Device mode not working on most CHT devices with an AXP288
-Host mode not working on devices with an INT3496 ACPI device
-Charger-type misdetection (always SDP) on devices with an INT3496 when the
USB role (always) gets initialized as host

Various Intel SoCs (Cherry Trail, Broxton and others) have an internal USB
role switch for swiching the OTG USB data lines between the xHCI host
controller and the dwc3 gadget controller.
Note on some Cherry Trail systems there is ACPI/AML code listening to
edge interrupts on the id-pin (through an _AIE ACPI method) and switching
the role between ROLE_HOST and ROLE_NONE based on the id-pin. Note it does
not set the role to ROLE_DEVICE, because device-mode is usually not used
under Windows.
The presence of AML code which modifies the cfg0 reg (on some systems)
means that our read/write/modify of cfg0 may race with the AML code
doing the same to avoid this we take the global ACPI lock while doing
the read/write/modify.

The xHCI controller on various Intel SoCs has an extended cap mmio-range
which contains registers to control the muxing to the xHCI (host mode)
or the dwc3 (device mode) and vbus-detection for the otg usb-phy.
Having a role-sw driver included in the xHCI code (under drivers/usb/host)
is not desirable. So this commit adds a simple handler for this extended
capability, which creates a platform device with the caps mmio region as
resource, this allows us to write a separate platform role-sw driver for
the role-switch.
Note this commit adds a call to the new xhci_ext_cap_init() function
to xhci_pci_probe(), it is added here because xhci_ext_cap_init() must
be called only once. If in the future we also want to handle ext-caps
on non pci xHCI HCDs from xhci_ext_cap_init() a call to it should also
be added to other bus probe paths.

Setting the mux to MUX_NONE and the switch to USB_SWITCH_DISCONNECT when
the data-role is device is not correct. Plenty of devices support
operating as USB device through a (separate) USB device controller.
We really need 2 different versions of USB_SWITCH_CONNECT,
USB_SWITCH_CONNECT_HOST and USB_SWITCH_DEVICE. Rather then modifying the
tcpc_usb_switch enum for this, simply remove it and switch to the
usb_role enum which provides exactly this, this will save use needing to
convert betweent the 2 enums when calling an usb-role-switch driver later.
Besides switching to the usb_role type, this commit also actually sets the
mux to TYPEC_MUX_USB and the switch to USB_ROLE_DEVICE instead of setting
both to none when the data-role is device.
This commit also makes tcpm_reset_port() call tcpm_mux_set(port,
TYPEC_MUX_NONE, USB_ROLE_NONE) so that the mux and switch
do _not_ stay in their last mode after a detach.

USB role switch is a device that can be used to choose the
data role for USB connector. With dual-role capable USB
controllers, the controller itself will be the switch, but
on some platforms the USB host and device controllers are
separate IPs and there is a mux between them and the
connector. On those platforms the mux driver will need to
register the switch.
With USB Type-C connectors, the host-to-device relationship
is negotiated over the Configuration Channel (CC). That
means the USB Type-C drivers need to be in control of the
role switch. The class provides a simple API for the USB
Type-C drivers for the control.
For other types of USB connectors (mainly microAB) the class
provides user space control via sysfs attribute file that
can be used to request role swapping from the switch.

USB Type-C connectors consist of various muxes and switches
that route the pins on the connector to the right locations.
The USB Type-C drivers need to be able to control the muxes,
as they are the ones that know things like the cable plug
orientation, and the current mode that was negotiated with
the partner.
This introduces a small API for registering and controlling
cable plug orientation switches, and separate small API for
registering and controlling pin multiplexer/demultiplexer
switches that are needed with Accessory/Alternate Modes.

For some userspace applications information on the number of
over-current conditions at specific USB hub ports is relevant.
In our case we have a series of USB hardware (using the cp210x driver)
which communicates using a proprietary protocol. These devices sometimes
trigger an over-current situation on some hubs. In case of such an
over-current situation the USB devices offer an interface for reducing
the max used power. As these conditions are quite rare and imply
performance reductions of the device we don't want to reduce the max
power always.
Therefore give user-space applications the possibility to react
adequately by introducing an over_current_counter in the usb port struct
which is exported via sysfs.

Pull x86/pti updates from Thomas Gleixner:
"Another set of melted spectrum updates:
- Iron out the last late microcode loading issues by actually
checking whether new microcode is present and preventing the CPU
synchronization to run into a timeout induced hang.
- Remove Skylake C2 from the microcode blacklist according to the
latest Intel documentation
- Fix the VM86 POPF emulation which traps if VIP is set, but VIF is
not. Enhance the selftests to catch that kind of issue
- Annotate indirect calls/jumps for objtool on 32bit. This is not a
functional issue, but for consistency sake its the right thing to
do.
- Fix a jump label build warning observed on SPARC64 which uses 32bit
storage for the code location which is casted to 64 bit pointer w/o
extending it to 64bit first.
- Add two new cpufeature bits. Not really an urgent issue, but
provides them for both x86 and x86/kvm work. No impact on the
current kernel"

Just when I had decided that flush_cache_range() was always called with
a valid context, Helge reported two cases where the
"BUG_ON(!vma->vm_mm->context);" was hit on the phantom buildd:

This indicates that we need to handle the no context case in
flush_cache_range() as we do in flush_cache_mm().
In thinking about this, I realized that we don't need to flush the TLB
when there is no context. So, I added context checks to the large flush
cases in flush_cache_mm() and flush_cache_range(). The large flush case
occurs frequently in flush_cache_mm() and the change should improve fork
performance.
The v2 version of this change removes the BUG_ON from flush_cache_page()
by skipping the TLB flush when there is no context. I also added code
to flush the TLB in flush_cache_mm() and flush_cache_range() when we
have a context that's not current. Now all three routines handle TLB
flushes in a similar manner.

"There's an important revert in this pull request that needs to go to
stable as it causes a corruption on big endian machines.
The other fix is for FIEMAP incorrectly reporting shared extents
before a sync and one fix for a crash in raid56.
So far we got only one report about the BE corruption, the stable
kernels were out for like a week, so hopefully the scope of the damage
is low"
