+EEPROMs (I2C)
+
+Required properties:
+
+ - compatible: Must be a "<manufacturer>,<model>" pair. The following <model>
+ values are supported (assuming "atmel" as manufacturer):
+
+ "atmel,24c00",
+ "atmel,24c01",
+ "atmel,24cs01",
+ "atmel,24c02",
+ "atmel,24cs02",
+ "atmel,24mac402",
+ "atmel,24mac602",
+ "atmel,spd",
+ "atmel,24c04",
+ "atmel,24cs04",
+ "atmel,24c08",
+ "atmel,24cs08",
+ "atmel,24c16",
+ "atmel,24cs16",
+ "atmel,24c32",
+ "atmel,24cs32",
+ "atmel,24c64",
+ "atmel,24cs64",
+ "atmel,24c128",
+ "atmel,24c256",
+ "atmel,24c512",
+ "atmel,24c1024",
+
+ If <manufacturer> is not "atmel", then a fallback must be used
+ with the same <model> and "atmel" as manufacturer.
+
+ Example:
+ compatible = "microchip,24c128", "atmel,24c128";
+
+ Supported manufacturers are:
+
+ "catalyst",
+ "microchip",
+ "ramtron",
+ "renesas",
+ "nxp",
+ "st",
+
+ Some vendors use different model names for chips which are just
+ variants of the above. Known such exceptions are listed below:
+
+ "renesas,r1ex24002" - the fallback is "atmel,24c02"
+
+ - reg: The I2C address of the EEPROM.
+
+Optional properties:
+
+ - pagesize: The length of the pagesize for writing. Please consult the
+ manual of your device, that value varies a lot. A wrong value
+ may result in data loss! If not specified, a safety value of
+ '1' is used which will be very slow.
+
+ - read-only: This parameterless property disables writes to the eeprom.
+
+ - size: Total eeprom size in bytes.
+
+ - no-read-rollover: This parameterless property indicates that the
+ multi-address eeprom does not automatically roll over
+ reads to the next slave address. Please consult the
+ manual of your device.
+
+ - wp-gpios: GPIO to which the write-protect pin of the chip is connected.
+
+Example:
+
+eeprom@52 {
+ compatible = "atmel,24c32";
+ reg = <0x52>;
+ pagesize = <32>;
+ wp-gpios = <&gpio1 3 0>;
+};
