From c580efb94abed05f99bb80245abe96cf5d49128c Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 2 Apr 2024 02:37:25 +0300 Subject: media: v4l2-subdev: Clearly document that the crop API won't be extended The V4L2 subdev crop API has been marked as obsolete, deprecated by the selection API. Despite this, it has recently been extended with streams support. In hindsight this was a mistake. Make sure it doesn't happen again by clearly documenting that no new extensions will be accepted.
