ae7eee56cd mfd: intel_soc_pmic_chtwc: Make Lenovo Yoga Tab 3 X90F DMI match less strict
There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.

Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.

fd0fec405d mfd: cros_ec: Update module description
The module description can be backtracked to commit e7c256fbfb
("platform/chrome: Add Chrome OS EC userspace device interface").

The description became out-of-date after a bunch of changes e.g:

- commit 5668bfdd90 ("platform/chrome: cros_ec_dev - Register cros-ec sensors").
- commit ea01a31b90 ("cros_ec: Split cros_ec_devs module").
- commit 5e0115581b ("cros_ec: Move cros_ec_dev module to drivers/mfd").

Update the description.

The ACSPCIE_PROXY_CTRL registers within the CTRL_MMR space of TI's J784S4
SoC are used to drive the reference clock to the PCIe Endpoint device via
the PAD IO Buffers. Add the compatible for allowing the PCIe driver to
obtain the regmap for the ACSPCIE_CTRL register within the System
Controller device-tree node in order to enable the PAD IO Buffers.

25aca9353e MAINTAINERS: Repair file entry in MARVELL 88PM886 PMIC DRIVER
Commit f53d3efa36 ("MAINTAINERS: Add myself for Marvell 88PM886 PMIC")
adds a file entry referring to drivers/regulators/88pm886-regulator.c,
but the directory is actually called drivers/regulator. Note that there is
no 's' at the end.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Repair the file entry in the MARVELL 88PM886 PMIC DRIVER section.

The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the PWM function using the platform device
registered by the core MFD driver.

The driver is derived from an initial implementation from NXP, available
in commit 113113742208 ("MLK-25922-1 pwm: adp5585: add adp5585 PWM
support") in their BSP kernel tree. It has been extensively rewritten.

738bbc660c gpio: adp5585: Add Analog Devices ADP5585 support
The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the GPIO function using the platform device
registered by the core MFD driver.

The driver is derived from an initial implementation from NXP, available
in commit 451f61b46b76 ("MLK-25917-2 gpio: adp5585-gpio: add
adp5585-gpio support") in their BSP kernel tree. It has been extensively
rewritten.

The ADP5585 is a 10/11 input/output port expander with a built in keypad

This driver supports the chip by modelling it as an MFD device, with two

The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
These bindings model the device as an MFD, and support the GPIO expander
and PWM functions.

These bindings support the GPIO and PWM functions.

Drop the existing adi,adp5585 and adi,adp5585-02 compatible strings from
trivial-devices.yaml. They have been added there by mistake as the
driver that was submitted at the same time used different compatible
strings. We can take them over safely.

017fa3e891 minmax: simplify and clarify min_t()/max_t() implementation
This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.

That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

4477b39c32 minmax: add a few more MIN_T/MAX_T users
Commit 3a7e02c040 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.

The complexity of those macros stems from two issues:

 (a) trying to use them in situations that require a C constant
     expression (in static initializers and for array sizes)

 (b) the type sanity checking

and MIN_T/MAX_T avoids both of these issues.

Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.

But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.

However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.

This does exactly that.

Which in turn will then allow for much simpler implementations of
min_t()/max_t().  All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.

We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

3415b10a03 kbuild: Fix '-S -c' in x86 stack protector scripts
After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:

  $ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
  clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]

This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.

'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.

All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.
