Subject: [PATCH v2 1/5] dt-bindings: remoteproc: sse710: Add the External Systems remote processors
Date: Thu, 22 Aug 2024 18:09:47 +0100 [thread overview]
Message-ID: <20240822170951.339492-2-abdellatif.elkhlifi@arm.com> (raw)
In-Reply-To: <20240822170951.339492-1-abdellatif.elkhlifi@arm.com>
Add devicetree binding schema for the External Systems remote processors
The External Systems remote processors are provided on the Corstone-1000
IoT Reference Design Platform via the SSE-710 subsystem.
For more details about the External Systems, please see Corstone SSE-710
subsystem features [1].
