This binding provides MEC15xx 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
description: |
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.
