-Subject: [PATCH 053/182] of: document bindings for reserved-memory nodes
-
-Reserved memory nodes allow for the reservation of static (fixed
-address) regions, or dynamically allocated regions for a specific
-purpose.

-+*** Reserved memory regions ***
-+
-+Reserved memory is specified as a node under the /reserved-memory node.
-+The operating system shall exclude reserved memory from normal usage
-+one can create child nodes describing particular reserved (excluded from
-+normal use) memory regions. Such memory regions are usually designed for
-+the special usage by various device drivers.
-+
-+Parameters for each memory region can be encoded into the device tree
-+with the following nodes:
-+
-+/reserved-memory node
-+---------------------
-+#address-cells, #size-cells (required) - standard definition
-+    - Should use the same values as the root node
-+ranges (required) - standard definition
-+    - Should be empty
-+
-+/reserved-memory/ child nodes
-+-----------------------------
-+Each child of the reserved-memory node specifies one or more regions of
-+reserved memory. Each child node may either use a 'reg' property to
-+specify a specific range of reserved memory, or a 'size' property with
-+optional constraints to request a dynamically allocated block of memory.
-+
-+Following the generic-names recommended practice, node names should
-+reflect the purpose of the node (ie. "framebuffer" or "dma-pool"). Unit
-+address (@<address>) should be appended to the name if the node is a
-+static allocation.
-+
-+Properties:
-+Requires either a) or b) below.
-+a) static allocation
-+   reg (required) - standard definition
-+b) dynamic allocation
-+   size (required) - length based on parent's #size-cells
-+                   - Size in bytes of memory to reserve.
-+   alignment (optional) - length based on parent's #size-cells
-+                        - Address boundary for alignment of allocation.
-+   alloc-ranges (optional) - prop-encoded-array (address, length pairs).
-+                           - Specifies regions of memory that are
-+                             acceptable to allocate from.
-+
-+If both reg and size are present, then the reg property takes precedence
-+and size is ignored.
-+
-+Additional properties:
-+compatible (optional) - standard definition
-+    - may contain the following strings:
-+        - shared-dma-pool: This indicates a region of memory meant to be
-+          used as a shared pool of DMA buffers for a set of devices. It can
-+          be used by an operating system to instanciate the necessary pool
-+          management subsystem if necessary.
-+        - vendor specific string in the form <vendor>,[<device>-]<usage>
-+no-map (optional) - empty property
-+    - Indicates the operating system must not create a virtual mapping
-+      of the region as part of its standard mapping of system memory,
-+      nor permit speculative access to it under any circumstances other
-+      than under the control of the device driver using the region.
-+reusable (optional) - empty property
-+    - The operating system can use the memory in this region with the
-+      limitation that the device driver(s) owning the region need to be
-+      able to reclaim it back. Typically that means that the operating
-+      system can use that region to store volatile or cached data that
-+      can be otherwise regenerated or migrated elsewhere.
-+
-+Linux implementation note:
-+- If a "linux,cma-default" property is present, then Linux will use the
-+  region for the default pool of the contiguous memory allocator.
-+
-+Device node references to reserved memory
-+-----------------------------------------
-+Regions in the /reserved-memory node may be referenced by other device
-+nodes by adding a memory-region property to the device node.
-+
-+memory-region (optional) - phandle, specifier pairs to children of /reserved-memory
-+
-+Example
-+-------
-+This example defines 3 contiguous regions are defined for Linux kernel:
-+one default of all device drivers (named linux,cma@72000000 and 64MiB in size),
-+one dedicated to the framebuffer device (named framebuffer@78000000, 8MiB), and
-+one for multimedia processing (named multimedia-memory@77000000, 64MiB).
