+* 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
+==================================
