Subject[PATCH 5.10 019/243] drm/ingenic: Switch IPU plane to type OVERLAY
Date
From: Paul Cercueil <paul@crapouillou.net>

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.

Fixes: fc1acf317b01 ("drm/ingenic: Add support for the IPU")
Cc: <stable@vger.kernel.org> # 5.8+
