Hello everyone,

I have submitted an RFC for the OV2312 camera sensor driver[1]. This 
patch series proposes the use of array controls to facilitate setting 
controls for both the RGB and IR streams coming out of the camera 
subdevice.

I would greatly appreciate your feedback and thoughts on this approach.
