    This binding provides MEC172x board gpio power rails resources to
    build and run samples/drives/espi in Zephyr.
    GPIOs required before performing a eSPI host-slave handshake

properties:
  pwrg-gpios:
    type: phandle-array
    required: true

      Board GPIO input used to detect that power rails are stable.

  rsm-gpios:
    type: phandle-array
    required: true

      Board GPIO output used to notify eSPI master to ackwnowledge
      power has stabilized and bare minimum initialization in eSPI slave
      is complete so eSPI master can proceed with eSPI handshake.
