+Fujitsu MB86S7x GPIO Controller
+-------------------------------
+
+Required properties:
+- compatible: Should be "fujitsu,mb86s70-gpio"
+- reg: Base address and length of register space
+- clocks: Specify the clock
+- gpio-controller: Marks the device node as a gpio controller.
+- #gpio-cells: Should be <2>. The first cell is the pin number and the
+  second cell is used to specify optional parameters:
+   - bit 0 specifies polarity (0 for normal, 1 for inverted).
+
+Examples:
+       gpio0: gpio@31000000 {
+               compatible = "fujitsu,mb86s70-gpio";
+               reg = <0 0x31000000 0x10000>;
+               gpio-controller;
+               #gpio-cells = <2>;
+               clocks = <&clk 0 2 1>;
+       };
