[PATCH v8 0/2] drivers/qcom: add Command DB support

[Lina Iyer]

Changes since v7:
	- Add reviewed-by tags
	- Fix example

Changes since v6:
        - Fix 'reg' property
        - Add reviewed-by tags

Changes since v5:
        - Remove indirection of command db start address
        - Rebase on top of 4.16

Changes since v4:
        - Address comments from Stephen and Bjorn

These patches add support for reading a shared memory database in the newer
QCOM SoCs called Command DB. With the new architecture on SDM845, shared
resources like clocks, regulators etc., have dynamic properties. These
properties may change based on external components, board configurations or
available feature set. A remote processor detects these parameters and fills up
the database with the resource and available state information. Platform
drivers that need these shared resources will need to query this database to
get the address and properties and vote for the state.

The information in the database is static. The database is read-only memory
location that is available for Linux. A pre-defined string is used as a key into
an entry in the database. Generally, platform drivers query the database only
at init to get the information they need.

[PATCH v8 1/2] drivers: qcom: add command DB driver

[Lina Iyer]

From: Mahesh Sivasubramanian <msivasub@codeaurora.org>

Command DB is a simple database in the shared memory of QCOM SoCs, that
provides information regarding shared resources. Some shared resources
in the SoC have properties that are probed dynamically at boot by the
remote processor. The information pertaining to the SoC and the platform
are made available in the shared memory. Drivers can query this
information using predefined strings.

Changes in v6:
	- Remove indirection and use the actual command db memory in DT

Changes in v5:
	- Use strncmp
	- Add check in probe to ensure the location at dictionary address
	  is same as the one specified in reserved-memory
	- Whitespace fixes
	- Comments updated

+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;
+		};
+	};

Hi Andy, David,

These patches have been reviewed by our peers and have recieved no
further comments in the past few weeks. Would you consider merging this
