 - reg: Should contain the register physical address and length for the
   pin controller.
+- clocks: Should contain a list of gate clk needed by the pin controller
+- clock-names: Should at least contain "pio_clk" which is used by the
+  base pin controller. In case of sun6i-a31 SoC, this property should
+  also contain the "pioL_clk" string.
 
 Please refer to pinctrl-bindings.txt in this directory for details of the
