2024-12-17platform/x86/amd/pmf: Enable Custom BIOS Inputs for PMF-TAShyam Sundar S K
Introduce support for passing custom BIOS inputs to the PMF-TA to assess BIOS input policy conditions. The PMF driver will adjust system settings based on these BIOS input conditions and their corresponding output actions.

2024-12-17platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from ↵Hans de Goede
i2c-i801 to dell-lis3lv02d Various Dell laptops have an lis3lv02d freefall/accelerometer sensor. The lis3lv02d chip has an interrupt line as well as an I2C connection to the system's main SMBus. The lis3lv02d is described in the ACPI tables by an SMO88xx ACPI device, but the SMO88xx ACPI fwnodes are incomplete and only list an IRQ resource. So far this has been worked around with some SMO88xx specific quirk code in the generic i2c-i801 driver, but it is not necessary to handle the Dell specific instantiation of i2c_client-s for SMO88xx ACPI devices there. The kernel already instantiates platform_device-s for these with an acpi:SMO88xx modalias. The drivers/platform/x86/dell/dell-smo8800.c driver binds to this platform device but this only deals with the interrupt resource. Add a drivers/platform/x86/dell/dell-lis3lv02d.c which will matches on the same acpi:SMO88xx modaliases and move the i2c_client instantiation from the generic i2c-i801 driver there. Moving the i2c_client instantiation has the following advantages: 1. This moves the SMO88xx ACPI device quirk handling away from the generic i2c-i801 module which is loaded on all Intel x86 machines to a module which will only be loaded when there is an ACPI SMO88xx device. 2. This removes the duplication of the SMO88xx ACPI Hardware ID (HID) table between the i2c-i801 and dell-smo8800 drivers. 3. This allows extending the quirk handling by adding new code and related module parameters to the dell-lis3lv02d driver, without needing to modify the i2c-i801 code.

2024-12-10ACPI: platform_profile: Allow multiple handlersMario Limonciello
Multiple drivers may attempt to register platform profile handlers, but only one may be registered and the behavior is non-deterministic for which one wins. It's mostly controlled by probing order. This can be problematic if one driver changes CPU settings and another driver notifies the EC for changing fan curves. Modify the ACPI platform profile handler to let multiple drivers register platform profile handlers and abstract this detail from userspace. To avoid undefined behaviors only offer profiles that are commonly advertised across multiple handlers. If any problems occur when changing profiles for any driver, then the drivers that were already changed remain changed and the legacy sysfs handler will report 'custom'.

2024-12-10platform/x86: acer-wmi: Implement proper hwmon supportArmin Wolf
After looking at the ACPI AML code, it seems that the command 0x0000 used with ACER_WMID_GET_GAMING_SYS_INFO_METHODID returns a bitmap of all supported sensor indices available through the 0x0001 command. Those sensor indices seem to include both temperature and fan speed sensors, with only the fan speed sensors being currently supported. Use the output of this new command to implement reliable sensor detection. This fixes detection of fans which do not spin during probe, as fans are currently being ignored if their speed is 0. Also add support for the new temperature sensor ids.

2024-12-10platform/x86: int3472: Make "pin number mismatch" message a debug messageHans de Goede
It seems that Windows is only using the ACPI GPIO resources and never looks at the part of the _DSM return value which encodes the pin number. For example on a Terra Pad 1262 v2 the following messages are printend: int3472-discrete INT3472:01: reset \_SB.GPI0 pin number mismatch _DSM 103 resource 359 int3472-discrete INT3472:01: powerdown \_SB.GPI0 pin number mismatch _DSM 207 resource 335 int3472-discrete INT3472:02: reset \_SB.GPI0 pin number mismatch _DSM 101 resource 357 Notice for the 2 reset pins that the _DSM value is off by 256, this is caused by there only being 8 bits reserved in the _DSM return value for the pin-number. As for the powerdown pin, testing has shown that the pin-number 335 from the ACPI GPIO resource is correct and the _DSM value is bogus. Lower the warning about these mismatches to a debug message and only look at the lower 8 bits of the GPIO resource pin numbers.

The Vexia EDU ATLA 10 tablet has an embedded controller instead of giving the os direct access to the charger + fuel-gauge ICs as is normal on tablets designed for Android. There is ACPI Battery device in the DSDT using the EC which should work except that it expects the I2C controller to be enumerated as an ACPI device and the tablet's BIOS enumerates all LPSS devices as PCI devices (and changing the LPSS BIOS settings from PCI -> ACPI does not work). Add a power_supply class driver for the Atla 10 EC to expert battery info to userspace. This is made part of the x86-android-tablets directory and Kconfig option because the i2c_client it binds to is instantiated by the x86-android-tablets kmod.

2024-12-10platform/x86/intel: bytcrc_pwrsrc: Optionally register a power_supply devHans de Goede
On some Android tablets with Crystal Cove PMIC the DSDT lacks an ACPI AC device to indicate whether a charger is plugged in or not. Add support for registering a "crystal_cove_pwrsrc" power_supply class device to indicate charger online status. This is made conditional on a "linux,register-pwrsrc-power_supply" boolean device-property to avoid registering a duplicate power_supply class device on devices where this is already handled by an ACPI AC device. Note the "linux,register-pwrsrc-power_supply" property is only used on x86/ACPI (non devicetree) devs and the devicetree-bindings maintainers have requested properties like these to not be added to the devicetree bindings, so the new property is deliberately not added to any bindings.
