-EEPROMs (SPI) compatible with Microchip Technology 93xx46 family.
-
-Required properties:
-- compatible : shall be one of:
-    "atmel,at93c46"
-    "atmel,at93c46d"
-    "atmel,at93c56"
-    "atmel,at93c66"
-    "eeprom-93xx46"
-    "microchip,93lc46b"
-- 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.
-
-Example:
-	eeprom@0 {
-		compatible = "eeprom-93xx46";
-		reg = <0>;
-		spi-max-frequency = <1000000>;
-		spi-cs-high;
-		data-size = <8>;
-		select-gpios = <&gpio4 4 GPIO_ACTIVE_HIGH>;
-	};
