  MIPI I3C Host Controller Interface

  The MIPI I3C HCI (Host Controller Interface) specification defines
  a common software driver interface to support compliant MIPI I3C
  host controller hardware implementations from multiple vendors.

  The hardware is self-advertising for differences in implementation
  capabilities, including the spec version it is based on, so there
  isn't much to describe here (yet).

  For details, please see:
  https://www.mipi.org/specifications/i3c-hci
