|  | Device-Tree bindings for drm hdmi driver | 
|  |  | 
|  | Required properties: | 
|  | - compatible: value should be one among the following: | 
|  | 1) "samsung,exynos5-hdmi" <DEPRECATED> | 
|  | 2) "samsung,exynos4210-hdmi" | 
|  | 3) "samsung,exynos4212-hdmi" | 
|  | 4) "samsung,exynos5420-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) optional flags and pull up/down. | 
|  | - clocks: list of clock IDs from SoC clock driver. | 
|  | a) hdmi: Gate of HDMI IP bus clock. | 
|  | b) sclk_hdmi: Gate of HDMI special clock. | 
|  | c) sclk_pixel: Pixel special clock, one of the two possible inputs of | 
|  | HDMI clock mux. | 
|  | d) sclk_hdmiphy: HDMI PHY clock output, one of two possible inputs of | 
|  | HDMI clock mux. | 
|  | e) mout_hdmi: It is required by the driver to switch between the 2 | 
|  | parents i.e. sclk_pixel and sclk_hdmiphy. If hdmiphy is stable | 
|  | after configuration, parent is set to sclk_hdmiphy else | 
|  | sclk_pixel. | 
|  | - clock-names: aliases as per driver requirements for above clock IDs: | 
|  | "hdmi", "sclk_hdmi", "sclk_pixel", "sclk_hdmiphy" and "mout_hdmi". | 
|  | - ddc: phandle to the hdmi ddc node | 
|  | - phy: phandle to the hdmi phy node | 
|  | - samsung,syscon-phandle: phandle for system controller node for PMU. | 
|  |  | 
|  | Example: | 
|  |  | 
|  | hdmi { | 
|  | compatible = "samsung,exynos4212-hdmi"; | 
|  | reg = <0x14530000 0x100000>; | 
|  | interrupts = <0 95 0>; | 
|  | hpd-gpio = <&gpx3 7 1>; | 
|  | ddc = <&hdmi_ddc_node>; | 
|  | phy = <&hdmi_phy_node>; | 
|  | samsung,syscon-phandle = <&pmu_system_controller>; | 
|  | }; |
