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 Required Properties: 10 - compatible: Should be "qnap,power-off" 11 12 - reg: Address and length of the register set for UART1 13 - clocks: tclk clock
