Merge branch 'next/hdmi-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/dt

From Kukjin Kim:
This is for adding support for DT based exynos5250 hdmi and it adds
device node for hdmi, mixer, hdmiphy and hdmiddc.

* 'next/hdmi-samsung' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: EXYNOS: removing exynos-drm device registration from non-dt platforms
  ARM: EXYNOS: add clocks for exynos5 hdmi
  ARM: dts: add device tree support for exynos5 hdmiddc
  ARM: dts: add device tree support for exynos5 hdmiphy
  ARM: dts: add device tree support for exynos5 mixer
  ARM: dts: add device tree support for exynos5 hdmi

+Device-Tree bindings for drm hdmi driver
+
+Required properties:
+- compatible: value should be "samsung,exynos5-hdmi".
+- reg: physical base address of the hdmi and length of memory mapped
+        region.
+- interrupts: interrupt number to the cpu.
+- hpd-gpio: following information about the hotplug gpio pin.
+        a) phandle of the gpio controller node.
+        b) pin number within the gpio controller.
+        c) pin function mode.
+        d) optional flags and pull up/down.
+        e) drive strength.
+
+Example:
+
+        hdmi {
+                compatible = "samsung,exynos5-hdmi";
+                reg = <0x14530000 0x100000>;
