+title: Renesas R-Car remote processor controller bindings

+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.

+  compatible:
+    const: renesas,rcar-cr7

+  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, ...).
