    1 * QNAP Power Off
    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
