new drivers only on drivers/phy/, sorry.
One more quesiton.
Should I also move Documentation/devicetree/bindings/usb/hi6220-usb.txt
to Documentation/devicetree/bindings/phy/?
I describing both usb controller and phy here, is it still should be put
under Documentation/devicetree/bindings/usb/?
Hisilicon hi6220 SoC USB controller
-----------------------------
usb controller is inherited from dwc2, refer dwc2.txt
-----
Required properties:
- compatible: "hisilicon,hi6220-usb"
Refer to dwc2.txt for dwc2 usb properties
PHY:
-----
Required properties:
- compatible: "hisilicon,hi6220-usb-phy"
- vcc-supply: phandle to the regulator that provides power to the PHY.
- clocks: phandle and clock specifier of the PHY clock.
- hisilicon,peripheral-syscon: phandle of syscon used to control peripheral.
- hisilicon,vbus-gpios: gpio of detecting vbus.
- hisilicon,id-gpios: gpio of detecting id.
Example:
sys_ctrl: syscon@f7030000 {
compatible = "hisilicon,sysctrl", "syscon";
reg = <0x0 0xf7030000 0x0 0x1000>;

hisilicon,id-gpios = <&gpio2 5 0>;
