[libcamera-devel] [PATCH v5 01/14] ipa: ipu3: Extend ipu3 ipa interface for sensor controls

[Jean-Michel Hautbois]

From: Han-Lin Chen <hanlinchen at chromium.org>

IPU3Event and IPU3Action use single ControlList for both libcamera and
V4L2 controls, and it's content could be either one based on the
context.  Extend IPU3Event and IPU3Action for sensor V4L2 controls, and
preserve the original one for only libcamera Controls to make the
content of an event more specific.
