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

Krzysztof Kozlowski
2020-08-12T16:30:07Z

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";
- };
