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 * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (21 commits) drm/exynos: Fix build error with exynos_drm_connector.c drm/exynos: Remove non-DT support in exynos_drm_fimd drm/exynos: Remove non-DT support in exynos_hdmi drm/exynos: Remove non-DT support in exynos_drm_g2d drm/exynos: Remove non-DT support in exynos_hdmiphy drm/exynos: Remove non-DT support in exynos_ddc drm/exynos: Make Exynos DRM drivers depend on OF drm/exynos: Consider fallback option to allocation fail drm/exynos: fimd: move platform data parsing to separate function drm/exynos: fimd: get signal polarities from device tree drm/exynos: fimd: replace struct fb_videomode with videomode drm/exynos: check a pixel format to a particular window layer drm/exynos: fix fimd pixel format setting drm/exynos: Add NULL pointer check drm/exynos: Remove redundant error messages drm/exynos: Add missing of.h header include drm/exynos: Remove redundant NULL check in exynos_drm_buf drm/exynos: add device tree support for rotator drm/exynos: Add missing includes drm/exynos: add runtime pm interfaces to g2d driver ...

+* Samsung Image Rotator
+
+Required properties:
+ - compatible : value should be one of the following:
+ (a) "samsung,exynos4210-rotator" for Rotator IP in Exynos4210
+ (b) "samsung,exynos4212-rotator" for Rotator IP in Exynos4212/4412
+ (c) "samsung,exynos5250-rotator" for Rotator IP in Exynos5250
+
+ - reg : Physical base address of the IP registers and length of memory
+ mapped region.
+
+ - interrupts : Interrupt specifier for rotator interrupt, according to format
+ specific to interrupt parent.
+
+ - clocks : Clock specifier for rotator clock, according to generic clock
+ bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)
+
+ - clock-names : Names of clocks. For exynos rotator, it should be "rotator".
+
+Example:
+ rotator@12810000 {
+ compatible = "samsung,exynos4210-rotator";
+ reg = <0x12810000 0x1000>;
+ interrupts = <0 83 0>;
+ clocks = <&clock 278>;
+ clock-names = "rotator";
+ };
