Subject: [PATCH] arm64: dts: qcom: qcs615: Add Command DB support
Date: Fri, 21 Feb 2025 15:39:57 +0800 [thread overview]
Message-ID: <20250221-add_command_db_support-v1-1-d60acbf913aa@quicinc.com> (raw)
Command DB is a database in the shared memory of QCOM SoCs, that
provides a mapping between resource key and the resource address for a
system resource managed by a remote processor. The data is stored in a
shared memory region and is loaded by the remote processor. Therefore,
enabling Command DB ensures that those resources function properly.
