| * QNAP Power Off | |
| QNAP NAS devices have a microcontroller controlling the main power | |
| supply. This microcontroller is connected to UART1 of the Kirkwood and | |
| Orion5x SoCs. Sending the charactor 'A', at 19200 baud, tells the | |
| microcontroller to turn the power off. This driver adds a handler to | |
| pm_power_off which is called to turn the power off. | |
| Required Properties: | |
| - compatible: Should be "qnap,power-off" | |
| - reg: Address and length of the register set for UART1 | |
| - clocks: tclk clock |
