Subject: [PATCH 0/9] Introduce Photonicat power management MCU driver

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.
