| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Must be "technologic,ts4800-gpio". |
| 5 | - #gpio-cells: Should be two. The first cell is the pin number. |
| 6 | - reg: Physical base address of the controller and length |
| 7 | of memory mapped region. |
| 8 | |
| 9 | Optional property: |
| 10 | - ngpios: See "gpio.txt" |
| 11 | |
| 12 | Example: |
| 13 | |
| 14 | gpio1: gpio { |
| 15 | compatible = "technologic,ts4800-gpio"; |
| 16 | reg = <0x10020 0x6>; |
| 17 | ngpios = <8>; |
| 18 | gpio-controller; |
| 19 | #gpio-cells = <2>; |
