* 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
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,
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
