+Hisilicon hi6220 SoC USB controller
+-----------------------------
[...]
+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,gpio-vbus: gpio of detecting vbus.
+- hisilicon,gpio-id: gpio of detecting id.
Actually, GPIO bindings say that GPIO properties should be named
"[<name>-]gpios".
+
+Example:
+
+ peripheral_ctrl: syscon@f7030000 {
+ compatible = "syscon";
+ reg = <0x0 0xf7030000 0x0 0x1000>;
+ };
+
+ usb2_phy: usbphy {
Please name it "usb-phy" as it better resembles "ethernet-phy"
standardized by ePAPR.
