[libcamera-devel] [PATCH v2 03/14] ipa: ipu3: Use sensor controls to update frameContext

[Jean-Michel Hautbois]

The pipeline handler populates the new sensorControls ControlList, to
have the effective exposure and gain values for the current frame. This
is done when a statistics buffer is received.

Make those values the frameContext::agc values for the frame when the
EventStatReady event is received.
