Hi All,
On some of the BYT devices, for DSI panels, the panel enable/disable signals
and backlight control are done using the Crystalcove PMIC. This series provides
support for the same and has been reviewed earlier on -
https://lkml.org/lkml/2015/4/29/301
This series addresses the review comments with one patch from last set already merged as -
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=efb0de55b6a2ec15fc424e660601f22ae2fa487a
Basically following are implemented -
1. GPIO control for panel enable/disable with GFX device as consumer
2. New PWM chip driver added for CRC PMIC based backlight control
3. i915 is modified to use the CRC gpio chip and the CRC PWM chip to do
backlight control. This is now added in the generic panel backlight
control infrastructure
All these patches have been tested on AsusT100 and working fine using
/sys/class/backlight/intel_backlight interface.
Patches were also verified on android-x86 tree for AsusT100.
