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

* 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";
};
