13description:
14  The PMIC GLINK service, running on a coprocessor on some modern Qualcomm
15  platforms and implement USB Type-C handling and battery management. This
16  binding describes the component in the OS used to communicate with the
17  firmware and connect it's resources to those described in the Devicetree,
18  particularly the USB Type-C controllers relationship with USB and DisplayPort
19  components.
