    1 Freescale i.MX6 DWC HDMI TX Encoder
    2 ===================================
    3 
    4 The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
    5 with a companion PHY IP.
    6 
    7 These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
    8 Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
    9 following device-specific properties.
   10 
   11 
   12 Required properties:
   13 
   14 - compatible : Shall be one of "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi".
   15 - reg: See dw_hdmi.txt.
   16 - interrupts: HDMI interrupt number
   17 - clocks: See dw_hdmi.txt.
   18 - clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
   19 - ports: See dw_hdmi.txt. The DWC HDMI shall have between one and four ports,
   20   numbered 0 to 3, corresponding to the four inputs of the HDMI multiplexer.
   21   Each port shall have a single endpoint.
   22 - gpr : Shall contain a phandle to the iomuxc-gpr region containing the HDMI
   23   multiplexer control register.
   24 
   25 Optional properties
   26 
   27 - ddc-i2c-bus: The HDMI DDC bus can be connected to either a system I2C master
   28   or the functionally-reduced I2C master contained in the DWC HDMI. When
   29   connected to a system I2C master this property contains a phandle to that
   30   I2C master controller.
   31 
   32 
   33 Example:
   34 
   35         gpr: iomuxc-gpr@20e0000 {
   36                 /* ... */
   37         };
   38 
   39         hdmi: hdmi@120000 {
   40                 #address-cells = <1>;
   41                 #size-cells = <0>;
   42                 compatible = "fsl,imx6q-hdmi";
   43                 reg = <0x00120000 0x9000>;
   44                 interrupts = <0 115 0x04>;
   45                 gpr = <&gpr>;
   46                 clocks = <&clks 123>, <&clks 124>;
   47                 clock-names = "iahb", "isfr";
   48                 ddc-i2c-bus = <&i2c2>;
   49 
   50                 port@0 {
   51                         reg = <0>;
   52 
   53                         hdmi_mux_0: endpoint {
   54                                 remote-endpoint = <&ipu1_di0_hdmi>;
   55                         };
   56                 };
   57 
   58                 port@1 {
   59                         reg = <1>;
   60 
   61                         hdmi_mux_1: endpoint {
   62                                 remote-endpoint = <&ipu1_di1_hdmi>;
   63                         };
   64                 };
   65         };
