162306a36Sopenharmony_ci* QNAP Power Off 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciQNAP NAS devices have a microcontroller controlling the main power 462306a36Sopenharmony_cisupply. This microcontroller is connected to UART1 of the Kirkwood and 562306a36Sopenharmony_ciOrion5x SoCs. Sending the character 'A', at 19200 baud, tells the 662306a36Sopenharmony_cimicrocontroller to turn the power off. 762306a36Sopenharmony_ci 862306a36Sopenharmony_ciSynology NAS devices use a similar scheme, but a different baud rate, 962306a36Sopenharmony_ci9600, and a different character, '1'. 1062306a36Sopenharmony_ci 1162306a36Sopenharmony_ciRequired Properties: 1262306a36Sopenharmony_ci- compatible: Should be "qnap,power-off" or "synology,power-off" 1362306a36Sopenharmony_ci 1462306a36Sopenharmony_ci- reg: Address and length of the register set for UART1 1562306a36Sopenharmony_ci- clocks: tclk clock 16
