   3 Required properties:
   4
   5   - compatible : should be "<manufacturer>,<type>", like these:
   6
   7         "atmel,24c00", "atmel,24c01", "atmel,24c02", "atmel,24c04",
   8         "atmel,24c08", "atmel,24c16", "atmel,24c32", "atmel,24c64",
   9         "atmel,24c128", "atmel,24c256", "atmel,24c512", "atmel,24c1024",
  10         "atmel,24c2048"
  11
  12         "catalyst,24c32"
  13
  14         "microchip,24c128"
  15
  16         "ramtron,24c64"
  17
  18         "renesas,r1ex24002"
  19
  20         The following manufacturers values have been deprecated:
  21         "at", "at24"
  22
  23          If there is no specific driver for <manufacturer>, a generic
  24          device with <type> and manufacturer "atmel" should be used.
  25          Possible types are:
  26          "24c00", "24c01", "24c02", "24c04", "24c08", "24c16", "24c32", "24c64",
  27          "24c128", "24c256", "24c512", "24c1024", "24c2048", "spd"
  28
  29   - reg : the I2C address of the EEPROM
  30
  31 Optional properties:
  32
  33   - pagesize : the length of the pagesize for writing. Please consult the
  34                manual of your device, that value varies a lot. A wrong value
  35                may result in data loss! If not specified, a safety value of
  36                '1' is used which will be very slow.
  37
  38   - read-only: this parameterless property disables writes to the eeprom

  40 Example:
  41
  42 eeprom@52 {
  43         compatible = "atmel,24c32";
  44         reg = <0x52>;
  45         pagesize = <32>;
  46 };
