Browse Source 
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@5f800000 {
compatible = "socionext,uniphier-pro4-soc-glue",
"simple-mfd", "syscon";
reg = <0x5f800000 0x2000>;
pinctrl: pinctrl {
compatible = "socionext,uniphier-pro4-pinctrl";
};
};
