[PATCH v4 2/2] dt-bindings: introduce Command DB for QCOM SoCs

+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 location of the
+		    Command DB in memory. Additionally, specify the address
+		    and size of the actual lacation in memory.
+
+Example:
+
+	reserved-memory {
+		[...]
+		qcom,cmd-db@c3f000c {
+			reg = <0x0 0xc3f000c 0x0 0x8>,
+			      <0x0 0x85fe0000 0x0 0x20000>;
+			compatible = "qcom,cmd-db";
+		};
+	};
