* Freescale i.MX/MXC GPIO controller
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,<soc>-gpio"
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts : Should be the port interrupt shared by all 32 pins, if
|
|
one number. If two numbers, the first one is the interrupt shared
|
|
by low 16 pins and the second one is for high 16 pins.
|
|
- gpio-controller : Marks the device node as a gpio controller.
|
|
- #gpio-cells : Should be two. The first cell is the pin number and
|
|
the second cell is used to specify optional parameters (currently
|
|
unused).
|
|
|
|
Example:
|
|
|
|
gpio0: gpio@73f84000 {
|
|
compatible = "fsl,imx51-gpio", "fsl,imx31-gpio";
|
|
reg = <0x73f84000 0x4000>;
|
|
interrupts = <50 51>;
|
|
gpio-controller;
|
|
#gpio-cells = <2>;
|
|
};
