Subject: [PATCH v1 2/2] media: i2c: add Sony IMX111 CMOS camera sensor driver
Add a v4l2 sub-device driver for the Sony IMX111 image sensor.
This is a camera sensor using the i2c bus for control and the
csi-2 bus for data.
The following features are supported:
- manual exposure, digital and analog gain control support
- pixel rate/link freq control support
- supported resolution up to 3280x2464 for single shot capture
- supported resolution up to 1920x1080 @ 30fps for video
- supported bayer order output SGBRG10 and SGBRG8
