1f3332532SSebastian Reichel* QNAP Power Off 2f3332532SSebastian Reichel 3f3332532SSebastian ReichelQNAP NAS devices have a microcontroller controlling the main power 4f3332532SSebastian Reichelsupply. This microcontroller is connected to UART1 of the Kirkwood and 5f3332532SSebastian ReichelOrion5x SoCs. Sending the character 'A', at 19200 baud, tells the 6*8cf46643SGuenter Roeckmicrocontroller to turn the power off. 7f3332532SSebastian Reichel 8f3332532SSebastian ReichelSynology NAS devices use a similar scheme, but a different baud rate, 9f3332532SSebastian Reichel9600, and a different character, '1'. 10f3332532SSebastian Reichel 11f3332532SSebastian ReichelRequired Properties: 12f3332532SSebastian Reichel- compatible: Should be "qnap,power-off" or "synology,power-off" 13f3332532SSebastian Reichel 14f3332532SSebastian Reichel- reg: Address and length of the register set for UART1 15f3332532SSebastian Reichel- clocks: tclk clock 16
