v1:
* Fix some format errors as suggested by Sergei.
* Modify gpio description to use gpiod API.
v2:
* Remove information about Hikey.
* Fix gpio description.
* Remove device_type of endpoint.
v3:
* Remove property typec-vbus-enable-val.
* Add description of pinctrl-names.
* Add example for "hisilicon,gpio-hubv1"
* Add flag in gpiod properties.

+Support usb hub and usb data role switch of Hisilicon HiKey960 Board.
+
+-----------------------------
+
+Required properties:
+- compatible: "hisilicon,gpio-hubv1","hisilicon,hikey960-usb"
+- typec-vbus-gpios: gpio to control the vbus of typeC port
+- otg-switch-gpios: gpio to switch DP & DM between the hub and typeC port
+- hub-vdd33-en-gpios: gpio to enable the power of hub
+- pinctrl-names: pin configuration state name ("default")
+- pinctrl-0: pinctrl config
+
+Example
+-----
+
+ hisi_hikey_usb: hisi_hikey_usb {
+ compatible = "hisilicon,hikey960-usb";
+ typec-vbus-gpios = <&gpio25 2 GPIO_ACTIVE_HIGH>;
+ otg-switch-gpios = <&gpio25 6 GPIO_ACTIVE_HIGH>;
+ hub-vdd33-en-gpios = <&gpio5 6 GPIO_ACTIVE_HIGH>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&usbhub5734_pmx_func>;
+
+ port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ hikey_usb_ep: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&dwc3_role_switch_notify>;
+ };
+ };
+ };
+
+ hisi_hikey_usb: hisi_hikey_usb {
+ compatible = "hisilicon,gpio-hubv1";
+ typec-vbus-gpios = <&gpio25 2 GPIO_ACTIVE_LOW>;
+ otg-switch-gpios = <&gpio25 6 GPIO_ACTIVE_HIGH>;
+ hub-vdd33-en-gpios = <&gpio5 6 GPIO_ACTIVE_HIGH>;

+ pinctrl-0 = <&usbhub5734_pmx_func>;
+
+ port {
