| * 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>; |
| }; |
