|
|
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>;
|
|
};
