+
+Required properties:
+- compatible: "ti,bone-capemgr"
+- eeprom: phandle to the EEPROM baseboard.
+          The EEPROM framework interface is use to obtain the data.
+
+Required children nodes:
+
+- baseboardmaps: Contains nodes, which each of the them defines a mapping from
+		 the baseboard EEPROM board-name ID to a DT friendly compatible
+		 string.
+
+  - board-name:      The baseboard EEPROM board name, i.e. A335BONE for the
+                     original beaglebone white.
+  - compatible-name: The DT friendly compatible string to be used for matching
+		     compatible capes, i.e. "ti,beaglebone"
+
+
+ - nvmem-cells: Defines the phandles of the nvmem cells of the baseboard and the
+                slots.
+ - nvmem-cells: Defines the names of the nvmem cells. Required to have at
+                least a baseboard cell name.
+
+ - #slots:	Defines how many slots are there.

+
+The format of the cape to be loaded is in a standard overlay format with
+the following root properties that are interpreted by the cape manager:
+
+Required properties:
+ - compatible: Should be compatible to the baseboard according to the
+               baseboard map value, i.e. "ti,beaglebone".
+ - part-numer: Should contain the part-number as stored in the EEPROM.
+ - version:    Should contain a list of all the version that are supported
+               by the single cape dtbo, i.e. "00A1".
+
+Optional properties:
+ - exclusive-use: A string list which state the resources this cape requires.
+                  No processing or matching to anything regarding the internal
+		  kernel state is performed; it's purpose is to guard against
+		  conflicts with other capes.
+ - priority:      A priority to be assigned when loading a cape. A lower value
+                  has higher priority. The purpose of the priority is to control
+		  which cape is loaded first in case of a conflict.
