1	Device-Tree bindings for drm hdmi driver
2	
3	Required 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	- reg: physical base address of the hdmi and length of memory mapped
9		region.
10	- interrupts: interrupt number to the cpu.
11	- hpd-gpio: following information about the hotplug gpio pin.
12		a) phandle of the gpio controller node.
13		b) pin number within the gpio controller.
14		c) optional flags and pull up/down.
15	- clocks: list of clock IDs from SoC clock driver.
16		a) hdmi: Gate of HDMI IP bus clock.
17		b) sclk_hdmi: Gate of HDMI special clock.
18		c) sclk_pixel: Pixel special clock, one of the two possible inputs of
19			HDMI clock mux.
20		d) sclk_hdmiphy: HDMI PHY clock output, one of two possible inputs of
21			HDMI clock mux.
22		e) mout_hdmi: It is required by the driver to switch between the 2
23			parents i.e. sclk_pixel and sclk_hdmiphy. If hdmiphy is stable
24			after configuration, parent is set to sclk_hdmiphy else
25			sclk_pixel.
26	- clock-names: aliases as per driver requirements for above clock IDs:
27		"hdmi", "sclk_hdmi", "sclk_pixel", "sclk_hdmiphy" and "mout_hdmi".
28	Example:
29	
30		hdmi {
31			compatible = "samsung,exynos4212-hdmi";
32			reg = <0x14530000 0x100000>;
33			interrupts = <0 95 0>;
34			hpd-gpio = <&gpx3 7 1>;
35		};
