-Command DB
----------
-
-Command DB is a database 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.
-
-Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for
-controlling shared resources. Depending on the board configuration the shared
-resource properties may change. These properties are dynamically probed by the
-remote processor and made available in the shared memory.
-
-The bindings for Command DB is specified in the reserved-memory section in
-devicetree. The devicetree representation of the command DB driver should be:
-
-Properties:
-- compatible:
- Usage: required
- Value type: <string>
- Definition: Should be "qcom,cmd-db"
-
-- reg:
- Usage: required
- Value type: <prop encoded array>
- Definition: The register address that points to the actual location of
- the Command DB in memory.
-
-Example:
-
- reserved-memory {
- [...]
- reserved-memory@85fe0000 {
- reg = <0x0 0x85fe0000 0x0 0x20000>;
- compatible = "qcom,cmd-db";
- no-map;
- };
- };
