Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-nextdrm-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

+* 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";
+	};
