+Command DB
+---------
+
+Command DB is a database that provides a mapping between resource key and the
s/between/between 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
s/SoC's/SoCs/
+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
s/bindings/node/
maybe?
+devicetree. The devicetree representation of the command DB driver should be:
Maybe drop this last sentence entirely.

+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.
s/lacation/location/
Will take care of these in the next spin.

+Example:

+ reserved-memory {
+ [...]
+ qcom,cmd-db@c3f000c {
+ reg = <0x0 0xc3f000c 0x0 0x8>,
+ <0x0 0x85fe0000 0x0 0x20000>;
+ compatible = "qcom,cmd-db";
+ };
