From 6d86278c9ddb2026727a6a9ba5a4550561aea940 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Mon, 29 Aug 2016 11:15:49 +0300 Subject: [PATCH] drm/omap: fix setting & clearing DOUBLESTRIDE The code that sets and clears DOUBLESTRIDE is only ran when using NV12. This is not correct, as we might first set the bith when using NV12, but never clear it when using other formats. Fix it so that when the bit is available (when the HW supports NV12) we always either set or clear the bit.
