[libcamera-devel] [PATCH v2 20/20] ipa: rpi: agc: When AGC channels are changed, start with the 1st channel

[Naushir Patuck]

Whenever the AGC active channels are changed, start with the first
channel listed. This allows applications to rely on a particular channel
being generated first. For example, multi-exposure HDR always wants the
short channel first.
