+TFP410 DPI to DVI encoder
+=========================
+
+Required properties:
+- compatible: "ti,tfp410"
+
+Optional properties:
+- powerdown-gpios: power-down gpio
+
+Required nodes:
+- Video port 0 for DPI input
+- Video port 1 for DVI output
+
+Example
+-------
+
+tfp410: encoder@0 {
+       compatible = "ti,tfp410";
+       powerdown-gpios = <&twl_gpio 2 GPIO_ACTIVE_LOW>;

+       ports {
+               #address-cells = <1>;
+               #size-cells = <0>;
+
