[RFC PATCH 1/2] dt-bindings: mtd: partitions: Document new dynamic-partitions node

[Ansuel Smith <ansuelsmth@gmail.com>]

Document new dynamic-partitions node used to provide an of node for
partition registred at runtime by parsers. This is required for nvmem
system to declare and detect nvmem-cells.

+title: Dynamic partitions
+
+description: |
+  This binding can be used on platforms which have partitions registered at
+  runtime by parsers or partition table present on the flash. Example are
+  partitions declared from smem parser or cmdlinepart. This will create an
+  of node for these dynamic partition where systems like Nvmem can get a
+  reference to register nvmem-cells.
+
+  The partition table should be a node named "dynamic-partitions".
+  Partitions are then defined as subnodes. Only the label is required
+  as any other data will be taken from the parser.
