+Socionext UniPhier Regulator Controller
+
+This describes the devicetree bindings for regulator controller implemented
+on Socionext UniPhier SoCs.
+
+USB3 Controller
+---------------
+
+Required properties:
+- compatible: Should be
+ "socionext,uniphier-pro4-usb3-regulator" - for Pro4 SoC
+ "socionext,uniphier-pxs2-usb3-regulator" - for PXs2 SoC
+ "socionext,uniphier-ld20-usb3-regulator" - for LD20 SoC
+ "socionext,uniphier-pxs3-usb3-regulator" - for PXs3 SoC
+- reg: Specifies offset and length of the register set for the device.
+- clocks: A list of phandles to the clock gate for USB3 glue layer.
+ According to the clock-names, appropriate clocks are required.
+- clock-names: Should contain
+ "gio", "link" - for Pro4 SoC
+ "link" - for others
+- resets: A list of phandles to the reset control for USB3 glue layer.
+ According to the reset-names, appropriate resets are required.
+- reset-names: Should contain
+ "gio", "link" - for Pro4 SoC
+ "link" - for others
+
+See Documentation/devicetree/bindings/regulator/regulator.txt
+for more details about the regulator properties.
+
+Example:
+
+ usb-glue@65b00000 {
+ compatible = "socionext,uniphier-ld20-dwc3-glue",
+ "simple-mfd";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x65b00000 0x400>;
+
+ usb_vbus0: regulators@100 {
+ compatible = "socionext,uniphier-ld20-usb3-regulator";
+ reg = <0x100 0x10>;
+ clock-names = "link";
+ clocks = <&sys_clk 14>;
+ reset-names = "link";
+ resets = <&sys_rst 14>;
+ };
+
+ phy {
+ ...
+ phy-supply = <&usb_vbus0>;
+ };
+
+ other nodes ...
+ };
