1 Aspeed GPIO controller Device Tree Bindings
2 -------------------------------------------
5 - compatible : Either "aspeed,ast2400-gpio" or "aspeed,ast2500-gpio"
7 - #gpio-cells : Should be two
8 - First cell is the GPIO line number
9 - Second cell is used to specify optional
12 - reg : Address and length of the register set for the device
13 - gpio-controller : Marks the device node as a GPIO controller.
14 - interrupts : Interrupt specifier (see interrupt bindings for
16 - interrupt-controller : Mark the GPIO controller as an interrupt-controller
20 - clocks : A phandle to the clock to use for debounce timings
22 The gpio and interrupt properties are further described in their respective
23 bindings documentation:
25 - Documentation/devicetree/bindings/gpio/gpio.txt
26 - Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
