 Required properties:
-- compatible: "allwinner,<soc>-pinctrl". Supported SoCs for now are:
-  sun5i-a13.
+- compatible: Should be one of the followings (depending on you SoC):
+  "allwinner,sun4i-a10-pinctrl"
+  "allwinner,sun5i-a10s-pinctrl"
+  "allwinner,sun5i-a13-pinctrl"
+  "allwinner,sun6i-a31-pinctrl"
+  "allwinner,sun6i-a31-r-pinctrl"
+  "allwinner,sun7i-a20-pinctrl"
 - reg: Should contain the register physical address and length for the
   pin controller.
