+Device-Tree bindings for the NXP TDA998x HDMI transmitter
+
+Required properties;
+ - compatible: must be "nxp,tda998x"
+
+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>
+
+Example:
+
+ tda998x: hdmi-encoder {
+ compatible = "nxp,tda998x";
+ reg = <0x70>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <27 2>; /* falling edge */
+ pinctrl-0 = <&pmx_camera>;
+ pinctrl-names = "default";
+ };
