| Freescale i.MX6 DWC HDMI TX Encoder |
| =================================== |
| |
| The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP |
| with a companion PHY IP. |
| |
| These DT bindings follow the Synopsys DWC HDMI TX bindings defined in |
| Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the |
| following device-specific properties. |
| |
| |
| Required properties: |
| |
| - compatible : Shall be one of "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi". |
| - reg: See dw_hdmi.txt. |
| - interrupts: HDMI interrupt number |
| - clocks: See dw_hdmi.txt. |
| - clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt. |
| - ports: See dw_hdmi.txt. The DWC HDMI shall have between one and four ports, |
| numbered 0 to 3, corresponding to the four inputs of the HDMI multiplexer. |
| Each port shall have a single endpoint. |
| - gpr : Shall contain a phandle to the iomuxc-gpr region containing the HDMI |
| multiplexer control register. |
| |
| Optional properties |
| |
| - ddc-i2c-bus: The HDMI DDC bus can be connected to either a system I2C master |
| or the functionally-reduced I2C master contained in the DWC HDMI. When |
| connected to a system I2C master this property contains a phandle to that |
| I2C master controller. |
| |
| |
| 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>; |
| }; |
| }; |
| }; |
