- * 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 character '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.
- Synology NAS devices use a similar scheme, but a different baud rate,
- 9600, and a different character, '1'.
- Required Properties:
- - compatible: Should be "qnap,power-off" or "synology,power-off"
- - reg: Address and length of the register set for UART1
- - clocks: tclk clock
