* mainboard, but they need some different treatment related to the display:
|
||||
* 1. The 830 uses a portrait LCD panel with a landscape touchscreen, requiring
|
||||
* the touchscreen driver to adjust the touch-coords to match the LCD.
|
||||
* 2. Both 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. This means that
|
||||
* the LP8557 i2c_client should only be instantiated on the 830.

|

* 2. Both 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

* 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. This means that
