[PATCH 0/2] media: i2c: Add onsemi AR0234 camera sensor driver

This series adds a driver for the onsemi AR0234 CMOS image sensor.
The AR0234 is a 1/2.6-inch global-shutter sensor with a 1940x1220
pixel array, capable of 1920x1200 resolution at up to 120 fps.
It supports MIPI CSI-2 output with 1 to 4 data lanes, raw Bayer
(8/10-bit) and monochrome formats, as well as DPCM 10->8 compression.

The driver has been tested with 2 and 4 lanes on an ARM64 Rockchip
RK3568 platform with a 27 MHz external clock. Both 8-bit and 10-bit
raw Bayer modes are functional.

Notes:
- 1-lane mode is currently disabled; attempts to use it produced no
  valid image.
