+Zodiac Inflight Innovations RAVE EEPROM Bindings
+
+RAVE SP EEPROM device is a "MFD cell" device exposing physical EEPROM
+attached to RAVE Supervisory Processor. It is expected that its Device
+Tree node is specified as a child of the node corresponding to the
+parent RAVE SP device (as documented in
+Documentation/devicetree/bindings/mfd/zii,rave-sp.txt)
+
+Required properties:
+
+- compatible: Should be "zii,rave-sp-eeprom"
+
+Optional properties:
+
+- zii,eeprom-name: Unique EEPROM identifier describing its function in the
+  system. Will be used as created NVMEM deivce's name.
+
+Data cells:
+
+Data cells are child nodes of eerpom node, bindings for which are
+documented in Documentation/bindings/nvmem/nvmem.txt
+
+Example:
+
+       rave-sp {
+               compatible = "zii,rave-sp-rdu1";
+               current-speed = <38400>;
+
+               eeprom@a4 {
+                       compatible = "zii,rave-sp-eeprom";
+                       reg = <0xa4 0x4000>;
+                       #address-cells = <1>;
+                       #size-cells = <1>;
+                       zii,eeprom-name = "main-eeprom";
+
+                       wdt_timeout: wdt-timeout@81 {
+                               reg = <0x81 2>;
+                       };
+               };
+       }
