cros-ec does not have an associated driver that uses the standard Linux USB-C driver class.
extcon is used to model the Type-C connector.(crbug.com/982932)

+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>;
