Merge tag 'imx-drm-fixes-2017-10-12' of git://git.pengutronix.de/git/pza/linux into drm-fixes
drm/imx: i.MX5 regression fix and i.MX6QP PRE/PRG stability fixes
- Disable channel burst locking on IPUv3EX (i.MX51) and IPUv3M (i.MX53).
This fixes a regression introduced by commit 790cb4c7c954 ("drm/imx: lock
scanout transfers for consecutive bursts").
- Give PRG a head start. Waiting for both double buffers to fill up before
enabling the IPU improves startup reliability.
- Avoid PRE control register updates during unsafe window, workaround for
ERR009624.
