Merge branch 'next/hdmi-samsung' of...

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

Documentation/devicetree/bindings/drm/exynos/hdmi.txt

+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>;
+		interrupts = <0 95 0>;
+		hpd-gpio = <&gpx3 7 0xf 1 3>;
+	};

Documentation/devicetree/bindings/drm/exynos/hdmiddc.txt

+Device-Tree bindings for hdmiddc driver
+
+Required properties:
+- compatible: value should be "samsung,exynos5-hdmiddc".
+- reg: I2C address of the hdmiddc device.
+
+Example:
+
+	hdmiddc {
+		compatible = "samsung,exynos5-hdmiddc";
+		reg = <0x50>;
+	};

Documentation/devicetree/bindings/drm/exynos/hdmiphy.txt

+Device-Tree bindings for hdmiphy driver
+
+Required properties:
+- compatible: value should be "samsung,exynos5-hdmiphy".
+- reg: I2C address of the hdmiphy device.
+
+Example:
+
+	hdmiphy {
+		compatible = "samsung,exynos5-hdmiphy";
+		reg = <0x38>;
+	};

Documentation/devicetree/bindings/drm/exynos/mixer.txt

+Device-Tree bindings for mixer driver
+
+Required properties:
+- compatible: value should be "samsung,exynos5-mixer".
+- reg: physical base address of the mixer and length of memory mapped
+	region.
+- interrupts: interrupt number to the cpu.
+
+Example:
+
+	mixer {
+		compatible = "samsung,exynos5-mixer";
+		reg = <0x14450000 0x10000>;
+		interrupts = <0 94 0>;
