Merge branch 'next/hdmi-samsung' of git://git.kernel.org/pub/scm/linu…

…x/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";

+		interrupts = <0 95 0>;
