| - compatible : Should be "st,nomadik-gpio". |
| - reg : Physical base address and length of the controller's registers. |
| - interrupts : The interrupt outputs from the controller. |
| - #gpio-cells : Should be two: |
| The first cell is the pin number. |
| The second cell is used to specify optional parameters: |
| - bits[3:0] trigger type and level flags: |
| 1 = low-to-high edge triggered. |
| 2 = high-to-low edge triggered. |
| 4 = active high level-sensitive. |
| 8 = active low level-sensitive. |
| - gpio-controller : Marks the device node as a GPIO controller. |
| - interrupt-controller : Marks the device node as an interrupt controller. |
| - gpio-bank : Specifies which bank a controller owns. |
| - st,supports-sleepmode : Specifies whether controller can sleep or not |
