+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>;
+ };
