    1 Device-Tree bindings for the NXP TDA998x HDMI transmitter
    2 
    3 Required properties;
    4   - compatible: must be "nxp,tda998x"
    5 
    6   - reg: I2C address
    7 
    8 Required node:
    9   - port: Input port node with endpoint definition, as described
   10         in Documentation/devicetree/bindings/graph.txt
   11 
   12 Optional properties:
   13   - interrupts: interrupt number and trigger type
   14 	default: polling
   15 
   16   - pinctrl-0: pin control group to be used for
   17 	screen plug/unplug interrupt.
   18 
   19   - pinctrl-names: must contain a "default" entry.
   20 
   21   - video-ports: 24 bits value which defines how the video controller
   22 	output is wired to the TDA998x input - default: <0x230145>
   23 
   24   - audio-ports: array of 8-bit values, 2 values per one DAI[1].
   25 	The first value defines the DAI type: TDA998x_SPDIF or TDA998x_I2S[2].
   26 	The second value defines the tda998x AP_ENA reg content when the DAI
   27 	in question is used. The implementation allows one or two DAIs. If two
   28 	DAIs are defined, they must be of different type.
   29 
   30   - nxp,calib-gpios: calibration GPIO, which must correspond with the
   31 	gpio used for the TDA998x interrupt pin.

   43 		interrupt-parent = <&gpio0>;
   44 		interrupts = <27 2>;		/* falling edge */
   45 		pinctrl-0 = <&pmx_camera>;
   46 		pinctrl-names = "default";
   47 		video-ports = <0x230145>;
   48 
   49 		#sound-dai-cells = <2>;
   50 			     /*	DAI-format	AP_ENA reg value */
   51 		audio-ports = <	TDA998x_SPDIF	0x04
   52 				TDA998x_I2S	0x03>;
   53 
   54 	};
