   1 EEPROMs (SPI) compatible with Microchip Technology 93xx46 family.
   2
   3 Required properties:
   4 - compatible : shall be one of:
   5     "atmel,at93c46d"
   6     "eeprom-93xx46"
   7 - data-size : number of data bits per word (either 8 or 16)
   8
   9 Optional properties:
  10 - read-only : parameter-less property which disables writes to the EEPROM
  11 - select-gpios : if present, specifies the GPIO that will be asserted prior to
  12   each access to the EEPROM (e.g. for SPI bus multiplexing)
  13
  14 Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
  15 apply.  In particular, "reg" and "spi-max-frequency" properties must be given.

  17 Example:
  18         eeprom@0 {
  19                 compatible = "eeprom-93xx46";
  20                 reg = <0>;
  21                 spi-max-frequency = <1000000>;
  22                 spi-cs-high;
  23                 data-size = <8>;
  24                 select-gpios = <&gpio4 4 GPIO_ACTIVE_HIGH>;
  25         };
