This is a note to let you know that I've just added the patch titled drm/ingenic: Switch IPU plane to type OVERLAY to the 5.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-ingenic-switch-ipu-plane-to-type-overlay.patch and it can be found in the queue-5.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 68b433fe6937cfa3f8975d18643d5956254edd6a Mon Sep 17 00:00:00 2001 From: Paul Cercueil <paul@xxxxxxxxxxxxxxx> Date: Mon, 29 Mar 2021 18:50:45 +0100 Subject: drm/ingenic: Switch IPU plane to type OVERLAY From: Paul Cercueil <paul@xxxxxxxxxxxxxxx> commit 68b433fe6937cfa3f8975d18643d5956254edd6a upstream. It should have been an OVERLAY from the beginning. The documentation stipulates that there should be an unique PRIMARY plane per CRTC.
