| Device-Tree bindings for HDMI Transmitter |
| |
| HDMI Transmitter |
| ================ |
| |
| The HDMI Transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP |
| with accompanying PHY IP. |
| |
| Required properties: |
| - #address-cells : should be <1> |
| - #size-cells : should be <0> |
| - compatible : should be "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi". |
| - gpr : should be <&gpr>. |
| The phandle points to the iomuxc-gpr region containing the HDMI |
| multiplexer control register. |
| - clocks, clock-names : phandles to the HDMI iahb and isrf clocks, as described |
| in Documentation/devicetree/bindings/clock/clock-bindings.txt and |
| Documentation/devicetree/bindings/clock/imx6q-clock.txt. |
| - port@[0-4]: Up to four port nodes with endpoint definitions as defined in |
| Documentation/devicetree/bindings/media/video-interfaces.txt, |
| corresponding to the four inputs to the HDMI multiplexer. |
| |
| Optional properties: |
| - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing |
| |
| example: |
| |
| gpr: iomuxc-gpr@020e0000 { |
| /* ... */ |
| }; |
| |
| hdmi: hdmi@0120000 { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| compatible = "fsl,imx6q-hdmi"; |
| reg = <0x00120000 0x9000>; |
| interrupts = <0 115 0x04>; |
| gpr = <&gpr>; |
| clocks = <&clks 123>, <&clks 124>; |
| clock-names = "iahb", "isfr"; |
| ddc-i2c-bus = <&i2c2>; |
| |
| port@0 { |
| reg = <0>; |
| |
| hdmi_mux_0: endpoint { |
| remote-endpoint = <&ipu1_di0_hdmi>; |
| }; |
| }; |
| |
| port@1 { |
| reg = <1>; |
| |
| hdmi_mux_1: endpoint { |
| remote-endpoint = <&ipu1_di1_hdmi>; |
| }; |
| }; |
| }; |
