2023-06-16platform/x86: apple-gmux: don't use be32_to_cpu and cpu_to_be32Orlando Chamberlain
Sparce doesn't seem to like using be32_to_cpu and cpu_to_be32 to convert values for the MMIO gmux to/from the host architecture. Instead use iowrite32be and ioread32be to always convert, which should be fine because apple-gmux is only used on x86 with is always little endian.

2023-06-14platform/x86/dell/dell-rbtn: Fix resources leaking on error pathMichal Wilczynski
Currently rbtn_add() in case of failure is leaking resources. Fix this by adding a proper rollback. Move devm_kzalloc() before rbtn_acquire(), so it doesn't require rollback in case of failure. While at it, remove unnecessary assignment of NULL to device->driver_data and unnecessary whitespace, plus add a break for the default case in a switch.

PMF driver maintains an internal config store for each PMF feature after the feature init happens.

2023-05-09platform/x86: lenovo-yogabook: Add keyboard backlight control to platform driverHans de Goede
On the Android yb1-x90f/l models there is not ACPI method to control the keyboard backlight brightness. Instead the second PWM controller is exposed directly to the OS there. Add support for controlling keyboard backlight brightness on the Android model by using the PWM subsystem to directly control the PWM. The Android model also requires explicitly turning the backlight off on suspend, which on the Windows model was done automatically.

2023-05-09platform/x86: lenovo-yogabook: Add platform driver supportHans de Goede
The Lenovo Yoga Book 1 comes in 2 versions. Version 1: The yb1-x91f/l currently supported by lenovo-yogabook-wmi, which has a WMI interface to deal with toggling the keyboard half between touch-keyboard and wacom-digitizer mode. Version 2: The yb1-x90f/l which is the same hardware shipping with Android as factory OS. This version has a very different BIOS and ACPI tables which lack the WMI interface. Instead the x86-android-tablets.ko code which does devices instantiation for devices missing from ACPI on various x86 Android tablets will instantiate a platform device for the keyboard half touch-kbd/digitizer toggle functionality. This patch adds a platform driver to the lenovo-yogabook code which binds to the platform device instantiated by x86-android-tablets.ko offering touch-kbd/digitizer toggle functionality on the Android model.

2023-05-09platform/x86: lenovo-yogabook: Use PMIC LED driver for pen icon LED controlHans de Goede
Use the (new) PMIC LED driver for pen icon LED control instead of using custom WMI calls for this. This will also work on the Android version of the Lenovo Yoga Book 1, where there is no WMI interface for this. The dev_id of the lookup is set using dev_name() so that it will also work for both the Windows YB1 WMI-device as well as the Android YB1 platform-device. While at it also move the gpio_lookup to using dev_name() for the dev_id. Note this also removes the need to turn of the LED during suspend since the PMIC LED driver now already does that.
