Subject: [PATCH v3 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
Camera module seems to be partially compatible with Nokia SMIA but it
lacks a few registers required for clock calculations and has different
vendor-specific per-mode configurations which makes it incompatible with
existing CCS driver.
