| 3 | Required properties: |
| 4 | - compatible: Should be "lsi,zevio-gpio" |
| 5 | - reg: Address and length of the register set for the device |
| 6 | - #gpio-cells: Should be two. The first cell is the pin number and the |

| 12 | compatible = "lsi,zevio-gpio"; |
| 13 | reg = <0x90000000 0x1000>; |
| 14 | gpio-controller; |
| 15 | #gpio-cells = <2>; |
