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.

Ensure that both the keyboard touchscreen and the digitizer have their driver bound after remove(). Without this modprobing lenovo-yogabook-wmi after a rmmod fails because lenovo-yogabook-wmi defers probing until both devices have their driver bound.

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. Add wmi_instance_count() and wmidev_instance_count() to allow WMI drivers to get the number of WMI object instances. Signed-off-by:

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. Add a x86_serdev_info entry to make the x86-android-tablets module manually setup the /sys/bus/serial device for the Bluetooth UART to fix Bluetooth not working due to this bug. Signed-off-by:

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.
