The Lenovo Yoga Tablet 2 Pro 1380F/L 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 + other devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module.

/*
|
|
* Various Lenovo models use a TI LP8557 LED backlight controller with its PWM
|
|
* input connected to a PWM output coming from the LCD panel's controller.
|
|
* The Android kernels have a hack in the i915 driver to write a non-standard
|
|
* panel specific DSI register to set the duty-cycle of the LCD's PWM output.
|
|
*
|
|
* To avoid having to have a similar hack in the mainline kernel program the
|
|
* LP8557 to directly set the level and use the lp855x_bl driver for control.
|
|
*
|
|
* The LP8557 can either be configured to multiply its PWM input and
|
|
* the I2C register set level (requiring both to be at 100% for 100% output);
|
|
* or to only take the I2C register set level into account.
|
|
*
|
|
* Multiplying the 2 levels is useful because this will turn off the backlight
|
|
* when the panel goes off and turns off its PWM output.
|
|
*
|
|
* But on some models the panel's PWM output defaults to a duty-cycle of
|
|
* much less then 100%, severely limiting max brightness. In this case
|
|
* the LP8557 should be configured to only take the I2C register into
|
|
* account and the i915 driver must turn off the panel and the backlight
|
|
* separately using e.g. VBT MIPI sequences to turn off the backlight.
