2023-05-09platform/x86: x86-android-tablets: Add Nextbook Ares 8A dataHans de Goede
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.

2023-05-09platform/x86: x86-android-tablets: Remove unnecessary invalid_aei_gpiochip ↵Hans de Goede
settings Since commit 5adc409340b1 ("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.

2023-04-06platform/x86: x86-android-tablets: Use LP8557 in direct mode on both the ↵Hans de Goede
Yoga 830 and the 1050 Both the Lenovo Yoga Tablet 2 830 and 1050 models use an TI LP8557 LED backlight controller. On the 1050 the LP8557's PWM input is connected to the PMIC's PWM output and everything works fine with the defaults programmed into the LP8557 by the BIOS. But on the 830 the LP8557's PWM input is connected to a PWM output coming from the LCD panel's controller. The Android code has a hack in the i915 driver to write the non-standard DSI reg 0x9f with the desired backlight level to set the duty-cycle of the LCD's PWM output. To avoid having to have a similar hack in the mainline kernel the LP8557 entry in lenovo_yoga_tab2_830_1050_i2c_clients instead just programs the LP8557 to directly set the level, ignoring the PWM input. So far we have only been instantiating the LP8557 i2c_client for direct backlight control on the 830 model. But we want hide/disable the intel_backlight interface on the 830 model to avoid having 2 backlight interfaces for the same LCD panel. And the 830 and 1050 share the same DMI strings. So this will hide the intel_backlight interface on the 1050 model too. To avoid this causing problems make the backlight handling consistent between the 2 models and always directly use the LP8557. This also simplifies the code.

2023-03-07platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq ↵Hans de Goede
C1010 The Peaq C1010 tablet has a special "Dolby" button. This button has a WMI interface, but this is broken in several ways: 1. It only supports polling 2. The value read on polling goes from 0 -> 1 for one poll on both edges of the button, with no way to tell which edge causes the poll to return 1. 3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID). There currently is a WMI driver for this, but it uses several kludges to work around these issues and is not entirely reliable due to 2. Replace the unreliable WMI driver by using the x86-android-tablets code to instantiate a gpio_keys device for this.
