HACK: media: v4l2-core: v4l2-ctrls-defs: Add custom IR exposure/gain
The OX05B1S camera sensor supports both RGB and IR stream exposure/gain
controls.
The sensor has one source pad which gives out 2 streams: IR
dominant (stream 0) and RGB dominant stream (stream 1). When programming
the exposure/gain settings for the camera from a user space application
like V4L2 user space API, we are unable to specify the stream for
which the exposure/gain change is required.
Hence, we have defined 3 custom control IDs for IR channel exposure,
anologue and digital gain control. These custom controls added for IR
channel are not an upstream acceptable solution and a better solution is
required in the V4L2 framework for exposure/gain control in multistream
sensors to remove this HACK.
