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. This driver adds a handler to 7 pm_power_off which is called to turn the power off. 8 9 Synology NAS devices use a similar scheme, but a different baud rate, 10 9600, and a different character, '1'. 11 12 Required Properties: 13 - compatible: Should be "qnap,power-off" or "synology,power-off" 14 15 - reg: Address and length of the register set for UART1 16 - clocks: tclk clock
