At times, when the mode transitions fail to happen, the current driver does not give enough debug information on why the transition failed or the default preset values did not load. Having an on-demand logs guarded by CONFIG would be helpful in such cases. Co-developed-by:

PMF driver maintains an internal config store for each PMF feature after the feature init happens. Having a debug mechanism to triage in-field issues w.r.t to mode switch not happening based on the OEM fed values via the ACPI method to PMF driver is becoming the need of the hour. Add support to get more ACPI debug spew guarded by a CONFIG. Co-developed-by:

The lenovo-yogabook-wmi.c code now consists of both a platform and a WMI driver and it does not use WMI at all when used on the Android model. Rename the module from lenovo-yogabook-wmi to lenovo-yogabook to reflect this. Signed-off-by:

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. Signed-off-by:

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.

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.

When yogabook_wmi_remove() runs yogabook_wmi_work might still be running and using the devices which yogabook_wmi_remove() puts. To avoid this move to explicitly cancelling the work rather then using devm_work_autocancel(). This requires also making the yogabook_backside_hall_irq handler non devm managed, so that it cannot re-queue the work while yogabook_wmi_remove() runs.

Currently, the WMI driver core knows how many instances of a given WMI object exist, but WMI drivers cannot access this information. At the same time, some current and upcoming WMI drivers want to have access to this information.

Modify the gpio_keys support in x86_android_tablet_init() for tablets which have more then 1 key/button which needs to be handled by the gpio_keys driver. This requires copying over the struct gpio_keys_button from the x86_gpio_button struct array to a new gpio_keys_button struct array, as an added benefit this allows marking the per model x86_gpio_button arrays __initconst so that they all can be freed after module init().

The Lenovo Yoga Book yb1-x90f/l has (another) bug in its DSDT where the UART resource for the BTH0 ACPI device contains "\\_SB.PCIO.URT1" as path to the UART. Note that is with a letter 'O' instead of the number '0' which is wrong.

The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module. Note the Ares 8A is the Cherry Trail (CHT) model, the regular Ares 8 is Bay Trail (BYT) based and was already supported. This also updates the comments for the BYT model to point out this is the BYT model. Signed-off-by:

Since commit 5adc4093 ("ACPI: x86: Introduce an acpi_quirk_skip_gpio_event_handlers() helper") the ACPI GPIO code will not register any GPIO event handlers at all for devices which have the ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS set in their DMI table entry in drivers/acpi/x86/utils.c . This includes the Nextbook Ares 8 and the Asus ME176C and TF103C models, so x86-android-tablets no longer needs to disable the GPIO event handlers on these, since they have never been registered at all.

Previously, some support for certain keys on the HP keyboard has been added already in commit 3ee5447b ("platform/x86: hp-wmi: Handle Omen Key event"), however this as tested did not allow even the fn+esc key on my HP Envy which uses the same keycode on my HP Envy x360 laptop to work --the keycode rather than being passed in as a separate int from WMI, was being passed in as the event_data for the HPWMI_OMEN_KEY event. This patch, as tested was able to properly get the keycode for fn+esc, and for fn+f12 which is supposed to be a programmable key according to HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key, however it did not previously have an entry in the sparse keymap. This patch preserves the original HPWMI_OMEN_KEY behavior for laptops that use it by only taking the keycode from the event_data only when the event_data is nonzero. Signed-off-by:

Previously, when the camera toggle switch was hit, the hp-wmi driver would report an invalid event code. By adding a case for that in the event handling switch statement we can eliminate that error code and enable a framework for potential further kernel handling of that key. This change was tested on my HP Envy x360 15-ey0023dx laptop, but it would likely work for any HP laptop with a camera toggle button. Now we emit an SW_CAMERA_LENS_COVER event, on a device that gets created on the first such event so as to not report incorrectly the state of the camera shutter before we can know its state.

The new generation of CPUs have granular control at a cluster level. Each package/die can have multiple power domains, which further can have multiple fabric clusters. The TPMI interface allows control at fabric cluster level. Use the updated uncore sysfs feature to expose controls at cluster level.
