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>;
|
|

|

|
|

|
|
