-UniPhier SoCs pin controller
-
-Required properties:
-- compatible: should be one of the following:
-    "socionext,uniphier-ld4-pinctrl"  - for LD4 SoC
-    "socionext,uniphier-pro4-pinctrl" - for Pro4 SoC
-    "socionext,uniphier-sld8-pinctrl" - for sLD8 SoC
-    "socionext,uniphier-pro5-pinctrl" - for Pro5 SoC
-    "socionext,uniphier-pxs2-pinctrl" - for PXs2 SoC
-    "socionext,uniphier-ld6b-pinctrl" - for LD6b SoC
-    "socionext,uniphier-ld11-pinctrl" - for LD11 SoC
-    "socionext,uniphier-ld20-pinctrl" - for LD20 SoC
-    "socionext,uniphier-pxs3-pinctrl" - for PXs3 SoC
-
-Note:
-The UniPhier pinctrl should be a subnode of a "syscon" compatible node.
-
-Example:
-	soc-glue@5f800000 {
-		compatible = "socionext,uniphier-pro4-soc-glue",
-			     "simple-mfd", "syscon";
-		reg = <0x5f800000 0x2000>;
-
-		pinctrl: pinctrl {
-			compatible = "socionext,uniphier-pro4-pinctrl";
-		};
-	};
