| 2 | |
| 3 | QNAP NAS devices have a microcontroller controlling the main power |
| 4 | supply. This microcontroller is connected to UART1 of the Kirkwood and |
| 5 | Orion5x SoCs. Sending the character 'A', at 19200 baud, tells the |
| 6 | microcontroller to turn the power off. |
| 7 | |
| 8 | Synology NAS devices use a similar scheme, but a different baud rate, |
| 9 | 9600, and a different character, '1'. |
| 10 | |
| 11 | Required Properties: |
| 12 | - compatible: Should be "qnap,power-off" or "synology,power-off" |
| 13 | |
| 14 | - reg: Address and length of the register set for UART1 |
| 15 | - clocks: tclk clock |
