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>;
};
};
};
