18c2ecf20Sopenharmony_ci* QNAP Power Off 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciQNAP NAS devices have a microcontroller controlling the main power 48c2ecf20Sopenharmony_cisupply. This microcontroller is connected to UART1 of the Kirkwood and 58c2ecf20Sopenharmony_ciOrion5x SoCs. Sending the character 'A', at 19200 baud, tells the 68c2ecf20Sopenharmony_cimicrocontroller to turn the power off. 78c2ecf20Sopenharmony_ci 88c2ecf20Sopenharmony_ciSynology NAS devices use a similar scheme, but a different baud rate, 98c2ecf20Sopenharmony_ci9600, and a different character, '1'. 108c2ecf20Sopenharmony_ci 118c2ecf20Sopenharmony_ciRequired Properties: 128c2ecf20Sopenharmony_ci- compatible: Should be "qnap,power-off" or "synology,power-off" 138c2ecf20Sopenharmony_ci 148c2ecf20Sopenharmony_ci- reg: Address and length of the register set for UART1 158c2ecf20Sopenharmony_ci- clocks: tclk clock 16
