| 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" |
| - 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". |
| - phy: it points to hdmiphy dt node. |
| Example: |
| |
| hdmi { |
| compatible = "samsung,exynos4212-hdmi"; |
| reg = <0x14530000 0x100000>; |
| interrupts = <0 95 0>; |
| hpd-gpio = <&gpx3 7 1>; |
| phy = <&hdmiphy>; |
| }; |
