2025-06-30Move FCH header to a location accessible by all archsMario Limonciello
A new header fch.h was created to store registers used by different AMD drivers. This header was included by i2c-piix4 in 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. Move the header to a location accessible by all architectures.

At the moment the atomisp has duplicate code for parsing Intel camera sensor GPIOS and calling the special 79234640-9e10-4fea-a5c1-b5aa8b19756f _DSM to get the GPIO type and map it to the sensor.

2025-05-08platform/x86: int3472: Stop using devm_gpiod_get()Hans de Goede
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.

2025-05-08platform/x86: asus-wmi: Refactor Ally suspend/resumeLuke D. Jones
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. Signed-off-by: Luke D.

2023-11-28platform/x86: asus-wmi: disable USB0 hub on ROG Ally before suspendLuke D. Jones
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. Signed-off-by: "Luke D.

2023-09-12platform/x86: asus-wmi: add support for ASUS screenpadLuke D. Jones
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. Signed-off-by: Luke D.

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.

Expose various CPU and dGPU tunables that are available on many ASUS ROG laptops. The tunables shown in sysfs will vary depending on the CPU and dGPU vendor. All of these variables are write only and there is no easy way to find what the defaults are. In general they seem to default to the max value the vendor sets for the CPU and dGPU package - this is not the same as the min/max writable value. Values written to these variables that are beyond the capabilities of the CPU are ignored by the laptop. Signed-off-by: Luke D.
