1 Aspeed GPIO controller Device Tree Bindings
2 -------------------------------------------
5 - compatible : Either "aspeed,ast2400-gpio", "aspeed,ast2500-gpio",
6 or "aspeed,ast2600-gpio".
8 - #gpio-cells : Should be two
9 - First cell is the GPIO line number
10 - Second cell is used to specify optional
13 - reg : Address and length of the register set for the device
14 - gpio-controller : Marks the device node as a GPIO controller.
15 - interrupts : Interrupt specifier (see interrupt bindings for
17 - interrupt-controller : Mark the GPIO controller as an interrupt-controller
21 - clocks : A phandle to the clock to use for debounce timings
22 - ngpios : Number of GPIOs controlled by this controller. Should be set
23 when there are multiple GPIO controllers on a SoC (ast2600).
25 The gpio and interrupt properties are further described in their respective
26 bindings documentation:
28 - Documentation/devicetree/bindings/gpio/gpio.txt
29 - Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
