SoC-specific version corresponding to the platform first followed by

the generic version.
|
2013-05-21 19:40:06 +08:00
|
|
|
|
|
|
|
|
- reg: Base address and length of each memory resource used by the GPIO
|
|
|
|
|
controller hardware module.
|
|
|
|
|
|
|
|
|
|
- interrupts: Interrupt specifier for the controllers interrupt.

|
2013-06-18 18:29:48 +08:00
|
|

Optional properties:
|
|
|
|
|
|
|
|
|
|
- clocks: Must contain a reference to the functional clock. The property is
|
|
|
|
|
mandatory if the hardware implements a controllable functional clock for
|
|
|
|
|
the GPIO instance.

The GPIO controller also acts as an interrupt controller. It uses the default
|
|
|
|
|
two cells specifier as described in Documentation/devicetree/bindings/
|
|
|
|
|
interrupt-controller/interrupts.txt.
