The intel_pmc_ipc() function uses ACPI_ALLOCATE_BUFFER to allocate memory
for the ACPI evaluation result but never frees it, causing a 192-byte
memory leak on each call.
This leak is triggered during network interface initialization when the
stmmac driver calls intel_mac_finish() -> intel_pmc_ipc().

The current set of DMI board IDs from the fixes branch is required to
reorder them in the for-next branch.

Adds the ppt_* and nv_* tuning knobs that are available via WMI methods
and adds proper min/max levels plus defaults.
The min/max are defined by ASUS and typically gained by looking at what
they allow in the ASUS Armoury Crate application - ASUS does not share
the values outside of this. It could also be possible to gain the AMD
values by use of ryzenadj and testing for the minimum stable value.
The general rule of thumb for adding to the match table is that if the
model range has a single CPU used throughout, then the DMI match can
omit the last letter of the model number as this is the GPU model.
If a min or max value is not provided it is assumed that the particular
setting is not supported. for example ppt_pl2_sppt_min/max is not set.
If a <ppt_setting>_def is not set then the default is assumed to be
<ppt_setting>_max
It is assumed that at least AC settings are available so that the
firmware attributes will be created - if no DC table is available
and power is on DC, then reading the attributes is -ENODEV.

The fw_attributes_class provides a much cleaner interface to all of the
attributes introduced to asus-wmi. This patch moves all of these extra
attributes over to fw_attributes_class, and shifts the bulk of these
definitions to a new kernel module to reduce the clutter of asus-wmi
with the intention of deprecating the asus-wmi attributes in future.
The work applies only to WMI methods which don't have a clearly defined
place within the sysfs and as a result ended up lumped together in
/sys/devices/platform/asus-nb-wmi/ with no standard API.
Where possible the fw attrs now implement defaults, min, max, scalar,
choices, etc. As en example dgpu_disable becomes:
/sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/
├── current_value
├── display_name
├── possible_values
└── type
as do other attributes.

regulator_unregister() already frees the associated GPIO device. On
ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to
random failures when other drivers (typically Intel THC) attempt to
allocate interrupts. The root cause is that the reference count of the
pinctrl_intel_platform module unexpectedly drops to zero when this
driver defers its probe.
This behavior can also be reproduced by unloading the module directly.
Fix the issue by removing the redundant release of the GPIO device
during regulator unregistration.

A new header fch.h was created to store registers used by different AMD

commit 624b0d5696a8 ("i2c: piix4, x86/platform: Move the SB800 PIIX4 FCH
definitions to <asm/amd/fch.h>"). To prevent compile failures on non-x86
archs i2c-piix4 was set to only compile on x86 by commit 7e173eb82ae9717
("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86").
This was not a good decision because loongarch and mips both actually
support i2c-piix4 and set it enabled in the defconfig.

The intent is to re-use the INT3472 code for parsing Intel camera sensor
GPIOs and mapping them to the sensor for the atomisp driver, which
currently has duplicate code.
On atomisp devices there is no special INT3472 ACPI device, instead
the Intel _DSM to get the GPIO type is part of the ACPI device for
the sensor itself.
To deal with this the mapping is done from ipu_bridge_init() instead of
from a platform-device probe() function, there is no device to tie
the lifetime of the gpiod_get() calls done by the INT3472 code to.
Switch from devm_gpiod_get() to plain gpiod_get() + explicit gpiod_put()
calls, to prepare for the code being re-used in the atomisp driver.

Adjust how the CSEE direct call hack is used.
The results of months of testing combined with help from ASUS to
determine the actual cause of suspend issues has resulted in this
refactoring which immensely improves the reliability for devices which
do not have the following minimum MCU FW version:
- ROG Ally X: 313
- ROG Ally 1: 319
For MCU FW versions that match the minimum or above the CSEE hack is
disabled and mcu_powersave set to on by default as there are no
negatives beyond a slightly slower device reinitialization due to the
MCU being powered off.
As this is set only at module load time, it is still possible for
mcu_powersave sysfs attributes to change it at runtime if so desired.

On almost all ASUS ROG series laptops the MCU used for the USB keyboard
also has a HID packet used for setting the brightness. This is usually
the same as the WMI method. But in some laptops the WMI method either
is missing or doesn't work, so we should default to the HID control.

Add support for vivobook fan profiles wmi call on the ASUS VIVOBOOK
to adjust power limits.
These fan profiles have a different device id than the ROG series
and different order. This reorders the existing modes.
As part of keeping the patch clean the throttle_thermal_policy_available
boolean stored in the driver struct is removed and
throttle_thermal_policy_dev is used in place (as on init it is zeroed).

Note these are added to include/linux/platform_data/x86/pmc_atom.h rather
then to include/linux/platform_data/x86/clk-pmc-atom.h because the former

ASUS have worked around an issue in XInput where it doesn't support USB
selective suspend, which causes suspend issues in Windows. They worked
around this by adjusting the MCU firmware to disable the USB0 hub when
the screen is switched off during the Microsoft DSM suspend path in ACPI.
The issue we have with this however is one of timing - the call the tells
the MCU to this isn't able to complete before suspend is done so we call
this in a prepare() and add a small msleep() to ensure it is done. This
must be done before the screen is switched off to prevent a variety of
possible races.
Further to this the MCU powersave option must also be disabled as it can
cause a number of issues such as:
- unreliable resume connection of N-Key
- complete loss of N-Key if the power is plugged in while suspended
Disabling the powersave option prevents this.
Without this the MCU is unable to initialise itself correctly on resume.

Add support for the WMI methods used to turn off and adjust the
brightness of the secondary "screenpad" device found on some high-end
ASUS laptops like the GX650P series and others.
There are some small quirks with this device when considering only the
raw WMI methods:
1. The Off method can only switch the device off
2. Changing the brightness turns the device back on
3. To turn the device back on the brightness must be > 1
4. When the device is off the brightness can't be changed (so it is
stored by the driver if device is off).
5. Booting with a value of 0 brightness (retained by bios) means the bios
will set a value of >0 <15
6. When the device is off it is "unplugged"
asus_wmi sets the minimum brightness as 20 in general use, and 60 for
booting with values <= min.
The ACPI methods are used in a new backlight device named asus_screenpad.

Siemens Simatic Industrial PCs can monitor the voltage of the CMOS
battery with two bits that indicate low or empty state. This can be GPIO
or PortIO based.
Here we model that as a hwmon voltage. The core driver does the PortIO
and provides boilerplate for the GPIO versions. Which are split out to
model runtime dependencies while allowing fine-grained kernel
configuration.
