description:
  Chrome OS devices have an Embedded Controller(EC) which has access to
  Type C port state. This node is intended to allow the host to read and
  control the Type C ports. This binding is compatible with both the
  cros-ec-typec and cros-ec-ucsi drivers. The cros-ec-typec driver
  supports the host command interface used by the Chrome OS EC with a
  built-in Type-C port manager and external Type-C Port Controller
  (TCPC). The cros-ec-ucsi driver supports the USB Type-C Connector
  System Software (UCSI) interface used by the Chrome OS EC when the
  platform has a separate power delivery controller (PDC). The node for
  this device should be under a cros-ec node like google,cros-ec-spi.
