+EEPROMs (I2C)
+
+Required properties:
+
+  - compatible : should be "<manufacturer>,<type>"
+                 If there is no specific driver for <manufacturer>, a generic
+                 driver based on <type> is selected. Possible types are:
+                 24c00, 24c01, 24c02, 24c04, 24c08, 24c16, 24c32, 24c64,
+                 24c128, 24c256, 24c512, 24c1024, spd
+
+  - 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
+
+Example:
+
+eeprom@52 {
+        compatible = "atmel,24c32";
+        reg = <0x52>;
+        pagesize = <32>;
