+Lattice MachXO2 Slave SPI FPGA Manager
+
+Lattice MachXO2 FPGAs support a method of loading the bitstream over
+'slave SPI' interface.
+
+See 'MachXO2ProgrammingandConfigurationUsageGuide.pdf' on www.latticesemi.com
+
+Required properties:
+- compatible: should contain "lattice,machxo2-slave-spi"
+- reg: spi chip select of the FPGA
+
+Example for full FPGA configuration:
+
+ fpga-region0 {
+ compatible = "fpga-region";
+ fpga-mgr = <&fpga_mgr_spi>;
+ #address-cells = <0x1>;
+ #size-cells = <0x1>;
+ };
+
+ spi1: spi@2000 {
+ ...
+
+ fpga_mgr_spi: fpga-mgr@0 {
+ compatible = "lattice,machxo2-slave-spi";
+ spi-max-frequency = <8000000>;
+ reg = <0>;
+ };

+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>;
+ };
+ };
+ }
