USB Type-C Detection Chip

Required properties :
- compatible : Must be "pericom,usb-type-c" or "ti,usb-type-c"
- reg: 7bit I2C slave address
- interrupt-parent: Should be phandle for the interrupt controller
                    that services interrupts for this device.
- interrupt: IRQ line
- <supply-name>-supply: handle to the regulator device tree node.
        "supply-name" is "vdd_io" regulator to drive I2C SCL and SDA lines.

Optional properties:
- pinctrl-names : This should be defined if a target uses pinctrl framework
  for INT_N and ENB pin. See "pinctrl" in
  Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.
  It should specify the names of the configs that pinctrl can install in driver.
  Following are the pinctrl config that can be installed:
      "usbc_int_default" : Default configuration of pins.
- <vendor-name>,enb-gpio : This corresponds to GPIO that is used to drive ENB
  pin. <vendor-name> can be 'pericom' or 'ti'.
  GPIO flag represents whether ENB pin is active-high(0) or active-low(1).
- <vendor-name>,disable-on-suspend : If present then disable chip on suspend if
  state is not attached. <vendor-name> can be 'pericom' or 'ti'.

Example :
	pericom-type-c@3d {
		compatible = "pericom,usb-type-c";
		reg = <0x3d>;
		vdd_io-supply = <&pm8950_l5>;
		interrupt-parent = <&msm_gpio>;
		interrupts = <102 2>;    /* MSM GPIO 102, TRIGGER_FALLING */
		pericom,enb-gpio = <&msm_gpio 101 0x1>;	/* active low ENB */
		pinctrl-names = "default";
		pinctrl-0 = <&usbc_int_default>;
	};
