   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
  11         "catalyst,24c32"
  12
  13         "microchip,24c128"
  14
  15         "ramtron,24c64"
  16
  17         "renesas,r1ex24002"
  18
  19         The following manufacturers values have been deprecated:
  20         "at", "at24"
  21
  22          If there is no specific driver for <manufacturer>, a generic
  23          device with <type> and manufacturer "atmel" should be used.
  24          Possible types are:
  25          "24c00", "24c01", "24c02", "24c04", "24c08", "24c16", "24c32", "24c64",
  26          "24c128", "24c256", "24c512", "24c1024", "spd"
  27
  28   - reg : the I2C address of the EEPROM
  29
  30 Optional properties:
  31
  32   - pagesize : the length of the pagesize for writing. Please consult the
  33                manual of your device, that value varies a lot. A wrong value
  34                may result in data loss! If not specified, a safety value of
  35                '1' is used which will be very slow.
  36
  37   - read-only: this parameterless property disables writes to the eeprom
  38
  39   - size: total eeprom size in bytes
  40
  41 Example:
  42
  43 eeprom@52 {
  44         compatible = "atmel,24c32";
  45         reg = <0x52>;
  46         pagesize = <32>;
  47 };
