Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Summary:
- Consider fallback option to gem allocation fail
. try to allocate physically non-contiguous memory
if iommu is supported when physically contiguous memory allocation
failed.
- Add runtime pm support to g2d driver
- Add device tree support
. add device tree support to rotator driver, make fimd driver get
signal polarities from device tree.
- some fixups
. correct pixel format setting to fimd driver, and consider pixel
format checking to a particular window layer.
- some cleanups
. replace fb_videomode with videomode.
. remove non-DT support
