1 Device-Tree bindings for HDMI Transmitter 2 3 HDMI Transmitter 4 ================ 5 6 The HDMI Transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP 7 with accompanying PHY IP. 8 9 Required properties: 10 - #address-cells : should be <1> 11 - #size-cells : should be <0> 12 - compatible : should be "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi". 13 - gpr : should be <&gpr>. 14 The phandle points to the iomuxc-gpr region containing the HDMI 15 multiplexer control register. 16 - clocks, clock-names : phandles to the HDMI iahb and isrf clocks, as described 17 in Documentation/devicetree/bindings/clock/clock-bindings.txt and 18 Documentation/devicetree/bindings/clock/imx6q-clock.txt. 19 - port@[0-4]: Up to four port nodes with endpoint definitions as defined in 20 Documentation/devicetree/bindings/media/video-interfaces.txt, 21 corresponding to the four inputs to the HDMI multiplexer. 22 23 Optional properties: 24 - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing 25 26 example: 27 28 gpr: iomuxc-gpr@020e0000 { 29 /* ... */ 30 }; 31 32 hdmi: hdmi@0120000 { 33 #address-cells = <1>; 34 #size-cells = <0>; 35 compatible = "fsl,imx6q-hdmi"; 36 reg = <0x00120000 0x9000>; 37 interrupts = <0 115 0x04>; 38 gpr = <&gpr>; 39 clocks = <&clks 123>, <&clks 124>; 40 clock-names = "iahb", "isfr"; 41 ddc-i2c-bus = <&i2c2>; 42 43 port@0 { 44 reg = <0>; 45 46 hdmi_mux_0: endpoint { 47 remote-endpoint = <&ipu1_di0_hdmi>; 48 }; 49 }; 50 51 port@1 { 52 reg = <1>; 53 54 hdmi_mux_1: endpoint { 55 remote-endpoint = <&ipu1_di1_hdmi>; 56 }; 57 }; 58 };
