1Freescale i.MX6 DWC HDMI TX Encoder
2===================================
3
4The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
5with a companion PHY IP.
6
7These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
8Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
9following device-specific properties.

11
12Required properties:
13
14- compatible : Shall be one of "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi".
15- reg: See dw_hdmi.txt.
16- interrupts: HDMI interrupt number
17- clocks: See dw_hdmi.txt.
18- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
19- ports: See dw_hdmi.txt. The DWC HDMI shall have between one and four ports,
20  numbered 0 to 3, corresponding to the four inputs of the HDMI multiplexer.
21  Each port shall have a single endpoint.
22- gpr : Shall contain a phandle to the iomuxc-gpr region containing the HDMI
23  multiplexer control register.
24
25Optional properties
26
27- ddc-i2c-bus: The HDMI DDC bus can be connected to either a system I2C master
28  or the functionally-reduced I2C master contained in the DWC HDMI. When
29  connected to a system I2C master this property contains a phandle to that
30  I2C master controller.
