+Device-Tree bindings for the NXP TDA998x HDMI transmitter
+
+Required properties;
+  - compatible: must be "nxp,tda998x"
+
+  - reg: I2C address
+
+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";
+        };
