EEPROMs (SPI) compatible with Microchip Technology 93xx46 family.
Required properties:
- compatible : shall be one of:
- data-size : number of data bits per word (either 8 or 16)
Optional properties:
- read-only : parameter-less property which disables writes to the EEPROM
- select-gpios : if present, specifies the GPIO that will be asserted prior to
each access to the EEPROM (e.g. for SPI bus multiplexing)
Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
apply. In particular, "reg" and "spi-max-frequency" properties must be given.
