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
|
||
|
|
|
||
|
|
