Subject: [PATCH 433/726] media: i2c: Add driver of Arducam 64MP camera
Add a driver for the Arducam 64MP camera sensor.
Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
currently only supports 2 lanes.
The following Bayer modes are currently available:
9152x6944 10-bit @ 2.7fps
4624x3472 10-bit (binned) @ 10fps
3840x2160 10-bit (cropped/binned) @ 20fps
2312x1736 10-bit (binned) @ 30fps
1920x1080 10-bit (cropped/binned) @ 60fps
1280x720 10-bit (cropped/binned) @ 120fps
