Huawei Matebook laptops uses Fn key and toggle to access F1-F12 keys.
Along with that, there is this feature called fn-lock that inverts the
behavior of this Fn key and the F1-F12 row.

Control battery charge thresholds through the battery API and driver's
attributes.
Setting battery charging thresholds can introduce a race condition with
MACH-WX9 where two or more threads are trying to read/write values
from/to EC memory.

Huawei Matebook laptops come with a WMI management interface that can
control various aspects of the device. This interface is also found on
the old Matebook X released in 2017.
Use that to control the mic mute LED.

Introduce quirks and module parameters. 3 quirks are added:
1. Fixes reporting brightness keys twice since it's already handled by
acpi-video.
2. Some models need a short delay when setting battery thresholds to
prevent a race condition when two processes read/write. (will be used later)
3. Matebook X (2017) handles micmute led through the "legacy" interface
which is not currently implemented. Use ACPI EC method to control
this led. (will be used later)
2 module parameters are added to enable this short delay and/or report
brightness keys through this driver.

Move from WMI driver to platform driver. This move is necessary since
the driver is no longer a hotkeys driver only. Platform driver makes it
easier for users to access sysfs attributes under (i.e.
/sys/devices/platform/huawei-wmi) compared to wmi driver.
Use WMI device UID, AMW0 has a UID of HWMI. WMI0 is the device name
and doesn't have a UID so keep it as it is.

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.
One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.
I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

We don't need explicit dependency of Goldfish kconfig option on various

Pull sound updates from Takashi Iwai:
"There have been some significant changes in the core side, both for
ALSA and ASoC, while lots of development have been seen in SOF, as
well as many small fixes/improvements for ASoC codecs and platforms.
Below is a highlight in this cycle:
Core:
- The unification of PCM vmalloc buffer allocation helpers into the
standard API
- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the
actual changes in drivers will be merged in 5.6
- Continued ASoC componentization works; now almost everything is a
common ASoC component object. A lot of refactoring and
simplification have been done along with it.
ASoC:
- Many fixes to the Sound Open Firmware (SOF) code
- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
HD-audio:
- Improved Intel DSP configuration / probe code for SOF
- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual
Others:
- Lots of refactoring and cleanups for FireWire; period-size sharing,
h/w IRQ interval configuration, clock recovery improvements, etc
- USB-audio: Scarlett mixer quirks
- Cleanups of PCM calls in various drivers (including media and USB)
to adapt the core API changes"

Pull MIPS updates from Paul Burton:
"The main MIPS changes for 5.5:
- Atomics-related code sees some rework & cleanup, most notably
allowing Loongson LL/SC errata workarounds to be more bulletproof &
their correctness to be checked at build time.
- Command line setup code is simplified somewhat, resolving various
corner cases.
- MIPS kernels can now be built with kcov code coverage support.
- We can now build with CONFIG_FORTIFY_SOURCE=y.
- Miscellaneous cleanups.
And some platform specific changes:
- We now disable some broken TLB functionality on certain Ingenic
systems, and JZ4780 systems gain some devicetree nodes to support
more devices.
- Loongson support sees a number of cleanups, and we gain initial
support for Loongson 3A R4 systems.
- We gain support for MediaTek MT7688-based GARDENA Smart Gateway
systems.
- SGI IP27 (Origin 2*) see a number of fixes, cleanups &
simplifications.
- SGI IP30 (Octane) systems are now supported"

Features of R4 revision of Loongson-3A:
- All R2/R3 features, including SFB, V-Cache, FTLB, RIXI, DSP, etc.
- Support variable ASID bits.
- Support MSA and VZ extensions.
- Support CPUCFG (CPU config) and CSR (Control and Status Register)
extensions.
- 64 entries of VTLB (classic TLB), 2048 entries of FTLB (8-way
set-associative).
Now 64-bit Loongson processors has three types of PRID.IMP: 0x6300 is
the classic one so we call it PRID_IMP_LOONGSON_64C (e.g., Loongson-2E/
2F/3A1000/3B1000/3B1500/3A2000/3A3000), 0x6100 is for some processors
which has reduced capabilities so we call it PRID_IMP_LOONGSON_64R
(e.g., Loongson-2K), 0xc000 is supposed to cover all new processors in
general (e.g., Loongson-3A4000+) so we call it PRID_IMP_LOONGSON_64G.

For APIC case of interrupt we don't fail a ->probe() of the driver,
which makes kernel to print a lot of warnings from the children.
We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
to be probed and failed
- fail the ->probe() of i2c-multi-instantiate
Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.

Allow to poll on the cros_ec device to receive the MKBP events.
The /dev/cros_[ec|fp|..] file operations now implements the poll
operation. The userspace can now receive specific MKBP events by doing
the following:
- Open the /dev/cros_XX file.
- Call the CROS_EC_DEV_IOCEVENTMASK ioctl with the bitmap of the MKBP
events it wishes to receive as argument.
- Poll on the file descriptor.
- When it gets POLLIN, do a read on the file descriptor, the first
queued event will be returned (using the struct
ec_response_get_next_event format: one byte of event type, then
the payload).
The read() operation returns at most one event even if there are several
queued, and it might be truncated if the buffer is smaller than the
event (but the caller should know the maximum size of the events it is
reading).
read() used to return the EC version string, it still does it when no
event mask or an empty event is set for backward compatibility (despite
nobody really using this feature).
This will be used, for example, by the userspace daemon to receive and
treat the EC_MKBP_EVENT_FINGERPRINT sent by the FP MCU.

Since the rpmsg_endpoint is created before probe is called, it's
possible that a host event is received during cros_ec_register, and
there would be some pending work in the host_event_work workqueue while
cros_ec_register is called.
If cros_ec_register fails, when the leftover work in host_event_work
run, the ec_dev from the drvdata of the rpdev could be already set to
NULL, causing kernel crash when trying to run cros_ec_get_next_event.
Fix this by creating the rpmsg_endpoint by ourself, and when
cros_ec_register fails (or on remove), destroy the endpoint first (to
make sure there's no more new calls to cros_ec_rpmsg_callback), and then
cancel all works in the host_event_work workqueue.

There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

The cros-ec-dev is a multifunction device that now doesn't implement any
chardev communication interface. MFD_CROS_EC_CHARDEV doesn't look
a good name to describe that device and can cause confusion. Hence
rename it to CROS_EC_DEV.

That's a driver to talk with the ChromeOS Embedded Controller via a
miscellaneous character device, it creates an entry in /dev for every
instance and implements basic file operations for communicating with the
Embedded Controller with an userspace application. The API is moved to
the uapi folder, which is supposed to contain the user space API of the
kernel.
Note that this will replace current character device interface
implemented in the cros-ec-dev driver in the MFD subsystem. The idea is
to move all the functionality that extends the bounds of what MFD was
designed to platform/chrome subsystem.

Now, the ChromeOS EC core driver has nothing related to an MFD device, so
move that driver from the MFD subsystem to the platform/chrome subsystem.

An MFD is a device that contains several sub-devices (cells). For instance,
the ChromeOS EC fits in this description as usually contains a charger and
can have other devices with different functions like a Real-Time Clock,
an Audio codec, a Real-Time Clock, ...
If you look at the driver, though, we're doing something odd. We have
two MFD cros-ec drivers where one of them (cros-ec-core) instantiates
another MFD driver as sub-driver (cros-ec-dev), and the latest
instantiates the different sub-devices (Real-Time Clock, Audio codec,
etc).

| |__ mfd-cell1
| |__ ...
|
|___ mfd-cellB (cros-ec-dev)
|__ mfd-cell0
|__ mfd-cell1
|__ ...
The problem that was trying to solve is to describe some kind of topology for
the case where we have an EC (cros-ec) chained with another EC
(cros-pd). Apart from that this extends the bounds of what MFD was
designed to do we might be interested on have other kinds of topology that
can't be implemented in that way.
Let's prepare the code to move the cros-ec-core part from MFD to
platform/chrome as this is clearly a platform specific thing non-related
to a MFD device.

Add the GET_BATT_PPID_INFO=0x8A command to the allowlist of accepted
telemetry commands. In addition, since this new command requires
verifying the contents of some of the arguments, I also restructure
the request to use a union of the argument structs. Also, zero out the
request buffer before each request, and change "whitelist" to
"allowlist".

Pull input updates from Dmitry Torokhov:
- input core allows hardware drivers to specify a [more precise]
timestamp (normally taken in top half) to better track velocity of
contacts
- input_dev instances now support "polling" mode so that drivers could
use the same object for polled and interrupt-driven operation. The
plan is to convert existing drivers and retire input_polled_dev API
- a new driver for the FlySky FS-iA6B RC receiver
- a refresh of BU21013 touchpad driver
- w90x900 keyboard and touchpad drivers are removed as the platform is
gone
- assorted fixes

Do not use the surfacepro3_button driver on newer Microsoft Surface
models, only use it on the Surface Pro 3 and 4. Newer models (5th, 6th
and possibly future generations) use the same device as the Surface Pro
4 to represent their volume and power buttons (MSHW0040), but their
actual implementation is significantly different. This patch ensures
that the surfacepro3_button driver is only used on the Pro 3 and 4
models, allowing a different driver to bind on other models.
