- 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>;
|
};
