description: |
This document defines the bindings for the remoteproc component that loads and
boots firmwares on the Renesas R-Car family chipset.
R-Car gen3 family may have a realtime processor, this processor shares peripheral
and RAM with the host processor with the same address map.
properties:
compatible:
const: renesas,rcar-cr7
resets:
maxItems: 1
power-domains:
maxItems: 1
memory-region:
description:
List of phandles to the reserved memory regions associated with the
remoteproc device. This is variable and describes the memories shared with
the remote processor (e.g. remoteproc firmware and carveouts, rpmsg
vrings, ...).
(see reserved-memory/reserved-memory.yaml in dtschema project)
