+iTE it6505 DP bridge bindings
+
+Required properties:
+ - compatible: "ite,it6505"
+ - reg: i2c address of the bridge
+ - ovdd-supply: I/O voltage
+ - pwr18-supply: Core voltage
+ - interrupts: interrupt specifier of INT pin
+ - reset-gpios: gpio specifier of RESET pin
+ - hpd-gpios:
+ Hotplug detect GPIO.
+ Indicates which GPIO should be used for hotplug detection
+ - port@[x]: SoC specific port nodes with endpoint definitions as defined
+ in Documentation/devicetree/bindings/display/mediatek/mediatek,dpi.txt
+
+Example:
+ dp-bridge@5c {
+ compatible = "ite,it6505";
+ interrupts = <152 IRQ_TYPE_EDGE_RISING 152 0>;
+ reg = <0x5c>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&it6505_pins>;
+ ovdd-supply = <&mt6358_vsim1_reg>;
+ pwr18-supply = <&it6505_pp18_reg>;
+ reset-gpios = <&pio 179 1>;
+ hpd-gpios = <&pio 9 0>;
+ extcon = <&usbc_extcon>;
+ };
