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>;

	};
