twl4030 GPIO controller bindings
|
|
|
|
Required properties:
|
|
- compatible:
|
|
- "ti,twl4030-gpio" for twl4030 GPIO controller
|
|
- #gpio-cells : Should be two.
|
|
- first cell is the pin number
|
|
- second cell is used to specify optional parameters (unused)
|
|
- gpio-controller : Marks the device node as a GPIO controller.
|
|
- #interrupt-cells : Should be 2.
|
|
- interrupt-controller: Mark the device node as an interrupt controller
|
|
The first cell is the GPIO number.
|
|
The second cell is not used.
|
|
|
|
Example:
|
|
|
|
twl_gpio: gpio {
|
|
compatible = "ti,twl4030-gpio";
|
|
#gpio-cells = <2>;
|
|
gpio-controller;
|
|
#interrupt-cells = <2>;
|
|
interrupt-controller;
|
|
};
