-Device-Tree bindings for tilcdc DRM TFP410 output driver
-
-Required properties:
- - compatible: value should be "ti,tilcdc,tfp410".
- - i2c: the phandle for the i2c device to use for DDC
-
-Recommended properties:
- - pinctrl-names, pinctrl-0: the pincontrol settings to configure
-   muxing properly for pins that connect to TFP410 device
- - powerdn-gpio: the powerdown GPIO, pulled low to power down the
-   TFP410 device (for DPMS_OFF)
-
-Example:
-
-	dvicape {
-		compatible = "ti,tilcdc,tfp410";
-		i2c = <&i2c2>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&bone_dvi_cape_dvi_00A1_pins>;
-		powerdn-gpio = <&gpio2 31 0>;
-	};
