1Device-Tree bindings for drm hdmi driver
2
3Required properties:
4- compatible: value should be one among the following:
5	1) "samsung,exynos5-hdmi" <DEPRECATED>
6	2) "samsung,exynos4210-hdmi"
7	3) "samsung,exynos4212-hdmi"
8	4) "samsung,exynos5420-hdmi"
9- reg: physical base address of the hdmi and length of memory mapped
10	region.
11- interrupts: interrupt number to the cpu.
12- hpd-gpio: following information about the hotplug gpio pin.
13	a) phandle of the gpio controller node.
14	b) pin number within the gpio controller.
15	c) optional flags and pull up/down.
16- clocks: list of clock IDs from SoC clock driver.
17	a) hdmi: Gate of HDMI IP bus clock.
18	b) sclk_hdmi: Gate of HDMI special clock.
19	c) sclk_pixel: Pixel special clock, one of the two possible inputs of
20		HDMI clock mux.
21	d) sclk_hdmiphy: HDMI PHY clock output, one of two possible inputs of
22		HDMI clock mux.
23	e) mout_hdmi: It is required by the driver to switch between the 2
24		parents i.e. sclk_pixel and sclk_hdmiphy. If hdmiphy is stable
25		after configuration, parent is set to sclk_hdmiphy else
26		sclk_pixel.
27- clock-names: aliases as per driver requirements for above clock IDs:
28	"hdmi", "sclk_hdmi", "sclk_pixel", "sclk_hdmiphy" and "mout_hdmi".
29- ddc: phandle to the hdmi ddc node
30- phy: phandle to the hdmi phy node
31- samsung,syscon-phandle: phandle for system controller node for PMU.

33Example:
34
35	hdmi {
36		compatible = "samsung,exynos4212-hdmi";
37		reg = <0x14530000 0x100000>;
38		interrupts = <0 95 0>;
39		hpd-gpio = <&gpx3 7 1>;
40		ddc = <&hdmi_ddc_node>;
41		phy = <&hdmi_phy_node>;
42		samsung,syscon-phandle = <&pmu_system_controller>;
43	};
