+CPU Subsystem Dump Driver
+
+The CPU Subsystem dump driver is used to dump various hardware entities
+like the instruction and data tlbs or the unified tlbs etc. to an
+allocated buffer. This allows the data to be analysed in case of corruption.
+
+Required Properties for the cpuss_dump node:
+-compatible = "qcom,cpuss-dump";
+
+All child nodes of cpuss_dump node are interpreted as the various hardware
+entities which need to be dumped.
+
+Required properties of the dump nodes
+
+- qcom,dump-node: phandle to the acutal cpuss hardware entity present
+		  in the cpu map
+- qcom,dump-id: The ID within the data dump table where this entry needs to
+		be added.
+
+Example:
+	msm_cpuss_dump {
+		compatible = "qcom,cpuss-dump";
+		qcom,itlb_dump100 {
+			qcom,dump-node = <&L1_itlb_100>;
+			qcom,dump-id = <34>;
+		};
+	};
