Initial support for the power management MCU in the Ariaboard Photonicat This patch series depends on Add support for Ariaboard Photonicat RK3568 [1] Currently implemented features: Implement serial communication protocol with MCU [2]. Support watchdog in MCU. Shutdown by power button and system notifies MCU to power-off. Read charger and battery supply voltage and simply calculate capacity. Read board temperature sensor. Set status of the network status LED. Read and set the MCU real-time clock date time.
