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>; };
