title: Huawei Matebook E Go Embedded Controller

description:
  Different from other Qualcomm Snapdragon sc8180x and sc8280xp-based
  machines, the Huawei Matebook E Go tablets use embedded controllers
  while others use a system called PMIC GLink which handles battery,
  UCSI, USB Type-C DP Alt Mode. In addition, Huawei's implementation
  also handles additional features, such as charging thresholds, FN
  lock, smart charging, tablet lid status, thermal sensors, and more.
