  11          Enable this driver to get read/write support to most I2C EEPROMs
  12          and compatible devices like FRAMs, SRAMs, ROMs etc. After you
  13          configure the driver to know about each chip on your target
  14          board.  Use these generic chip names, instead of vendor-specific
  15          ones like at24c64, 24lc02 or fm24c04:
  16
  17             24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
  18             24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024, 24c2048
  19
  20          Unless you like data loss puzzles, always be sure that any chip
  21          you configure as a 24c32 (32 kbit) or larger is NOT really a
  22          24c16 (16 kbit) or smaller, and vice versa. Marking the chip
  23          as read-only won't help recover from this. Also, if your chip
  24          has any software write-protect mechanism you may want to review the
  25          code to make sure this driver won't turn it on by accident.
  26
  27          If you use this with an SMBus adapter instead of an I2C adapter,
  28          full functionality is not available.  Only smaller devices are
  29          supported (24c16 and below, max 4 kByte).

  31          This driver can also be built as a module.  If so, the module
  32          will be called at24.

  51          If you say yes here you get read-only access to the EEPROM data
  52          available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
  53          EEPROMs could theoretically be available on other devices as well.
  54
  55          This driver is deprecated and will be removed soon, please use the
  56          better at24 driver instead.

  58          This driver can also be built as a module.  If so, the module

 104          on digsy_mtc board. You have to additionally select Microwire
 105          EEPROM 93XX46 driver. sysfs entries will be created for that
