Subject: [PATCH] dt-bindings: pinctrl: uniphier: add UniPhier pinctrl binding

The driver has been in the tree for a while, but its binding document
is missing.  Hence, here it is.

+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@...00000 {
+		compatible = "socionext,uniphier-pro4-soc-glue",
+			     "simple-mfd", "syscon";
+		reg = <0x5f800000 0x2000>;
+
+		pinctrl: pinctrl {
+			compatible = "socionext,uniphier-pro4-pinctrl";
+		};
+	};
