+* Qualcomm Technologies, Inc. MSM Camera SMMU
+
+The MSM camera SMMU device provides SMMU context bank definitions
+for all HW blocks that need to map IOVA to physical memory. These
+definitions consist of various properties that define how the
+IOVA address space is laid out for each HW block in the camera
+subsystem.
+
+=======================
+Required Node Structure
+=======================
+The camera SMMU device must be described in three levels of device nodes. The
+first level describes the overall SMMU device. Within it, second level nodes
+describe individual context banks that map different stream ids. There can
+also be second level nodes describing firmware device nodes. Each HW block
+such as IFE, ICP maps into these second level device nodes. All context bank
+specific properties that define how the IOVA is laid out is contained within
+third level device nodes within the second level device nodes.
+
+During the kernel initialization all the devices are probed recursively and
+a device pointer is created for each context bank keeping track of the IOVA
+mapping information.
+
+Duplicate regions of the same type are not allowed within the same
+context bank. All context banks must contain an IO region at the very least.
+
+==================================
+First Level Node - CAM SMMU device
+==================================
+- compatible
+ Usage: required
+ Value type: <string>
+ Definition: Should be "qcom,msm-cam-smmu".
+
+===================================================================
+Second Level Node - CAM SMMU context bank device or firmware device
+===================================================================
+- compatible
+ Usage: required
+ Value type: <string>
+ Definition: Should be "qcom,msm-cam-smmu-cb" or "qcom,msm-cam-smmu-fw-dev".
+
+- memory-region
+ Usage: optional
+ Value type: <phandle>
+ Definition: Should specify the phandle of the memory region for firmware.
+ allocation
+
+- iommus
+ Usage: required
+ Value type: <phandle>
+ Definition: Should specify the phandle of the iommu sid.
+
+- label
+ Usage: required
+ Value type: <string>
+ Definition: Should specify a string label to identify the context bank.
+
+=============================================
+Third Level Node - CAM SMMU memory map device
+=============================================
+- iova-region-name
+ Usage: required
+ Value type: <string>
+ Definition: Should specify a string label to identify the IOVA region.
+
+- iova-region-start
+ Usage: required
+ Value type: <u32>
+ Definition: Should specify start IOVA for region.
+
+- iova-region-len
+ Usage: required
+ Value type: <u32>
+ Definition: Should specify length for IOVA region.
+
+- iova-region-id
+ Usage: required
+ Value type: <u32>
+ Definition: Should specify the numerical identifier for IOVA region.
+ Allowed values are: 0x00 to 0x03
+ - Firmware region: 0x00
+ - Shared region: 0x01
+ - Scratch region: 0x02
+ - IO region: 0x03
