Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[1].
Accelerometer
lis2hh12
accelerometer is not so stable for auto screen rotation, which suggests you to use fixed portrait or landscape mode.
Touchkey
Touchkey type is unknown, so there is nothing done for it.
Ambient Light/Proximity Sensor
The driver for cm36686
ambient light/proximity sensor is not available.
