1* QNAP Power Off
2
3QNAP NAS devices have a microcontroller controlling the main power
4supply. This microcontroller is connected to UART1 of the Kirkwood and
5Orion5x SoCs. Sending the character 'A', at 19200 baud, tells the
6microcontroller to turn the power off. This driver adds a handler to
7pm_power_off which is called to turn the power off.
8
9Synology NAS devices use a similar scheme, but a different baud rate,
109600, and a different character, '1'.
