2025-05-08platform/x86: int3472: Stop using devm_gpiod_get()Hans de Goede3-2/+11
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.

commit ba47652ba655 ("media: meye: remove this deprecated driver") removed the meye driver but left behind the code in sony-laptop.c which that driver used to call. Remove the sony_pic_camera_command() function, and the set of defines (SONY_PIC_COMMAND_*) in a header used for the interface and the static helpers it called. Cleanup remaining #defines.

2025-05-08platform/x86: ISST: Do Not Restore SST MSRs on CPU Online OperationSrinivas Pandruvada1-21/+0
During CPU offline/online operations, the hardware retains MSR settings. Even if all CPUs are offlined, the package does not lose its MSR settings. Therefore, it is unnecessary to restore MSRs which are modified during the online operation, and this extra step can be removed.

SST-TF revision 2 supports a higher number of cores per bucket, as the current limit of 256 cores may be insufficient. To accommodate this, a new offset, "SST_TF_INFO-8," is introduced, allowing for a higher core count. Utilize this offset instead of the current "SST_TF_INFO-1" offset, based on SST-TF revision 2 or higher, and if there is a non-zero core count in any bucket.

The TUXEDO Sirius 16 Gen1 and TUXEDO Sirius 16 Gen2 devices have a per-key controllable RGB keyboard backlight. The firmware API for it is implemented via WMI. To make the backlight userspace configurable this driver emulates a LampArray HID device and translates the input from hidraw to the corresponding WMI calls. This is a new approach as the leds subsystem lacks a suitable UAPI for per-key keyboard backlights, and like this no new UAPI needs to be established. The handle_* functions an corresponding structs are named based on the HID spec: HID Usage Tables 1.6 -> 26 Lighting And Illumination Page (0x59) Signed-off-by: Werner Sembach <wse@tuxedocomputers.com> Link: https://lore.kernel.org/r/20250425210043.342288-2-wse@tuxedocomputers.com Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
