define KernelPackage/gl-mifi-mcu/description
  Interfaces with GL-MiFI Power monitoring MCU with a soft UART
  and provides Battery SOC, Temperature and charging data at
  /proc/gl_mifi_mcu.
  This feature is supported from GL-MiFi PCB revision v2.6.2.
  The content of /proc/gl_mifi_mcu is JSON as received from the
  UART and will frequenty contain corrupted data due to soft UART
  unreliability. User application must validate the data.
