Hello,
Add a v4l2 sub-device driver for Dongwoon's DW9768 lens voice coil.
This is a voice coil module using the i2c bus to control the focus position.
The DW9768 can control the position with 10 bits value and
consists of two 8 bit registers show as below:
register 0x04(DW9768_REG_POSITION):
+---+---+---+---+---+---+---+---+
|D07|D06|D05|D04|D03|D02|D01|D00|
+---+---+---+---+---+---+---+---+
register 0x03:
+---+---+---+---+---+---+---+---+
|---|---|---|---|---|---|D09|D08|
+---+---+---+---+---+---+---+---+
This driver support :
- set DW9768 to standby mode once suspend and turn it back to active if resume
- set the position via V4L2_CID_FOCUS_ABSOLUTE ctrl
