[libcamera-devel] [PATCH v4 3/4] include: linux: Add V4L2_CID_NOTIFY_GAIN_XXX controls

[David Plowman]

Add the V4L2 controls

V4L2_CID_NOTIFY_GAIN_RED
V4L2_CID_NOTIFY_GAIN_GREENR
V4L2_CID_NOTIFY_GAIN_BLUE
V4L2_CID_NOTIFY_GAIN_GREENB

In future some sensors may expose these controls when they want to be
informed of the gains the downstream processing will apply, though the
sensor will not apply the gains itself.
