dt-bindings: nvmem: Add binding for RAVE SP EEPROM driver

Browse source 
Add Device Tree bindings for RAVE SP EEPROM driver - an MFD cell of
parent RAVE SP driver (documented in
Documentation/devicetree/bindings/mfd/zii,rave-sp.txt).

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>;
};
};
}
