From 181c9bfe4b37a36075c91b9e16ce8c99ed0d9b7b Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 18 Oct 2016 12:13:15 +0200 Subject: [PATCH] drm/imx: ipuv3-plane: request modeset if plane offsets changed If the framebuffer pixel format is planar YUV and unchanged, but the U or V plane offsets change, do not return an error, but request a modeset instead.
