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 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. 32 33 Example: 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 };
