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>;
};
};
};
