13  RAVE SP EEPROM device is a "MFD cell" device exposing physical EEPROM
14  attached to RAVE Supervisory Processor. It is expected that its Device
15  Tree node is specified as a child of the node corresponding to the
16  parent RAVE SP device (as documented in
17  Documentation/devicetree/bindings/mfd/zii,rave-sp.yaml)
