Subject: [PATCH 01/11] dt-bindings: extcon: ptn5150: Convert binding to DT schema

Convert the ptn-5150 extcon driver bindings to DT schema format using
json-schema.  The differences with original bindings document:
 - Use "gpios" suffix for the "int" and "vbus" gpio,
 - Skip generic properties like "reg" or "pinctrl".

-* PTN5150 CC (Configuration Channel) Logic device
-
-PTN5150 is a small thin low power CC logic chip supporting the USB Type-C
-connector application with CC control logic detection and indication functions.
-It is interfaced to the host controller using an I2C interface.
-
-Required properties:
-- compatible: should be "nxp,ptn5150"
-- reg: specifies the I2C slave address of the device
-- int-gpio: should contain a phandle and GPIO specifier for the GPIO pin
-	connected to the PTN5150's INTB pin.
-- vbus-gpio: should contain a phandle and GPIO specifier for the GPIO pin which
-	is used to control VBUS.
-- pinctrl-names : a pinctrl state named "default" must be defined.
-- pinctrl-0 : phandle referencing pin configuration of interrupt and vbus
-	control.
-
-Example:
-	ptn5150@1d {
-		compatible = "nxp,ptn5150";
-		reg = <0x1d>;
-		int-gpio = <&msmgpio 78 GPIO_ACTIVE_HIGH>;
-		vbus-gpio = <&msmgpio 148 GPIO_ACTIVE_HIGH>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&ptn5150_default>;
-		status = "okay";
-	};
