-Peripheral core reset in glue layer
------------------------------------
-
-Some peripheral core reset belongs to its own glue layer. Before using
-this core reset, it is necessary to control the clocks and resets to enable
-this layer. These clocks and resets should be described in each property.
-
-Required properties:
-- compatible: Should be
-    "socionext,uniphier-pro4-usb3-reset" - for Pro4 SoC USB3
-    "socionext,uniphier-pro5-usb3-reset" - for Pro5 SoC USB3
-    "socionext,uniphier-pxs2-usb3-reset" - for PXs2 SoC USB3
-    "socionext,uniphier-ld20-usb3-reset" - for LD20 SoC USB3
-    "socionext,uniphier-pxs3-usb3-reset" - for PXs3 SoC USB3
-    "socionext,uniphier-pro4-ahci-reset" - for Pro4 SoC AHCI
-    "socionext,uniphier-pxs2-ahci-reset" - for PXs2 SoC AHCI
-    "socionext,uniphier-pxs3-ahci-reset" - for PXs3 SoC AHCI
-- #reset-cells: Should be 1.
-- reg: Specifies offset and length of the register set for the device.
-- clocks: A list of phandles to the clock gate for the glue layer.
-	According to the clock-names, appropriate clocks are required.
-- clock-names: Should contain
-    "gio", "link" - for Pro4 and Pro5 SoCs
-    "link"        - for others
-- resets: A list of phandles to the reset control for the glue layer.
-	According to the reset-names, appropriate resets are required.
-- reset-names: Should contain
-    "gio", "link" - for Pro4 and Pro5 SoCs
-    "link"        - for others
-
-Example:
-
-	usb-glue@65b00000 {
-		compatible = "socionext,uniphier-ld20-dwc3-glue",
-			     "simple-mfd";
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges = <0 0x65b00000 0x400>;
-
-		usb_rst: reset@0 {
-			compatible = "socionext,uniphier-ld20-usb3-reset";
-			reg = <0x0 0x4>;
-			#reset-cells = <1>;
-			clock-names = "link";
-			clocks = <&sys_clk 14>;
-			reset-names = "link";
-			resets = <&sys_rst 14>;
-		};
-
-		regulator {
-			...
-		};
-
-		phy {
-			...
-		};
-		...
-	};
