Subject: [RESEND PATCH v5 3/7] dt-bindings: remoteproc: Add processor identifier property
Date: Tue, 21 May 2024 14:24:54 +0200 [thread overview]
Message-ID: <20240521122458.3517054-4-arnaud.pouliquen@foss.st.com> (raw)
In-Reply-To: <20240521122458.3517054-1-arnaud.pouliquen@foss.st.com>
Add the "st,proc-id" property allowing to identify the remote processor.
This ID is used to define an unique ID, common between Linux, U-boot and
OP-TEE to identify a coprocessor.
This ID will be used in request to OP-TEE remoteproc Trusted Application
to specify the remote processor.
