7 1.1 #gpio-cells
9 Property: #gpio-cells
13 Description: The #gpio-cells property defines the number of cells required
17 1.2 gpio-controller
19 Property: gpio-controller
23 Description: The presence of a gpio-controller property defines a node as a
24 GPIO controller node.
27 1.3 pin-count
29 Property: pin-count
33 Description: The pin-count property defines the number of GPIO pins.
39 #gpio-cells = <3>;
42 gpio-controller;
44 interrupt-parent = <&PIC>;
45 pin-count = <50>
54 Value type: <prop-encoded-array> encoded as arbitrary number of GPIO
59 consists of an arbitrary number of GPIO specifiers.
62 parent GPIO controller and remaining cells are defined by the
64 information like pin number, direction and various flags.
71 3. GPIO controller specifier
76 pin: 0-MAX GPIO pin number.
80 can be supported by the controller. For details please refer
81 to controller's GPIO reference manual.
