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