v3:
fix typo and add -EPROBE_DEFER of regulator, pointed by Peter
v2:
address comments from Sergei and Peter
add hi6220_phy_setup(false) code
v1:
hi6220 usb controller is inherited from dwc2
add phy accordingly
support otg gadget/host

OK, thanks for the info, I don't know this at all.
So even usb phy should be put under drivers/phy/.
Will change that.

I would like to remind you the thread at
http://thread.gmane.org/gmane.linux.kernel/1858137. I have a USB PHY driver
here that depends on notify_connect/notify_disconnect, which are not currently
provided by the generic phy infrastructure (drivers/phy/). What would be
acceptable solution for this case?

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";
