ASUS WMI driver got a big refactoring in order to support the TUF Gaming
laptops. Besides that, the regression with backlight being permanently off
on various EeePC laptops has been fixed.
Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
Intel PMC core driver has been extended to be ACPI enumerated
if the DSDT provides device with _HID "INT33A1". This allows
to convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
From now on the Intel Speed Select Technology is supported thru
a corresponding driver. This driver provides an access to the features
of the ISST, such as Performance Profile, Core Power, Base frequency and
Turbo Frequency.
Mellanox platform drivers has been refactored and now extended
to support more systems, including new coming ones.
The OLPC XO-1.75 platform is now supported.
CB4063 Beckhoff Automation board is using PMC clocks,
provided via pmc_atom driver, for ethernet controllers in a way
that they can't be managed by the clock driver. The quirk
has been extended to cover this case.
Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more models
based on the same platform.
Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
has been provided. It required some extension of the generic WMI library,
which allows to propagate opaque context to the ->probe() of the
individual drivers.
This release includes debugfs clean up from Greg KH for several drivers
that drop return code check and make debugfs absence or failure non-fatal.
Miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers.

Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

- A fair pile of RST conversions, many from Mauro. These create more

that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos, and one

- Various improvements to the build system, including automatic markup of
function() references because some people, for reasons I will never
understand, were of the opinion that :c:func:``function()`` is
unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc.

The old_memmap flow in efi_call_phys_prolog() performs numerous memory
allocations, and either does not check for failure at all, or it does
but fails to propagate it back to the caller, which may end up calling
into the firmware with an incomplete 1:1 mapping.
So let's fix this by returning NULL from efi_call_phys_prolog() on
memory allocation failures only, and by handling this condition in the
caller. Also, clean up any half baked sets of page tables that we may
have created before returning with a NULL return value.
Note that any failure at this level will trigger a panic() two levels
up, so none of this makes a huge difference, but it is a nice cleanup
nonetheless.

This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.
This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

Move the x86 EFI earlyprintk implementation to a shared location under
drivers/firmware and tweak it slightly so we can expose it as an earlycon
implementation (which is generic) rather than earlyprintk (which is only
implemented for a few architectures)
This also involves switching to write-combine mappings by default (which
is required on ARM since device mappings lack memory semantics, and so
memcpy/memset may not be used on them), and adding support for shared
memory framebuffers on cache coherent non-x86 systems (which do not
tolerate mismatched attributes).
Note that 32-bit ARM does not populate its struct screen_info early
enough for earlycon=efifb to work, so it is disabled there.
