   3 config EEPROM_AT24
   4         tristate "I2C EEPROMs / RAMs / ROMs from most vendors"
   5         depends on I2C && SYSFS
   6         help
   7           Enable this driver to get read/write support to most I2C EEPROMs
   8           and compatible devices like FRAMs, SRAMs, ROMs etc. After you
   9           configure the driver to know about each chip on your target
  10           board.  Use these generic chip names, instead of vendor-specific
  11           ones like at24c64, 24lc02 or fm24c04:
  12
  13              24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
  14              24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
  15
  16           Unless you like data loss puzzles, always be sure that any chip
  17           you configure as a 24c32 (32 kbit) or larger is NOT really a
  18           24c16 (16 kbit) or smaller, and vice versa. Marking the chip
  19           as read-only won't help recover from this. Also, if your chip
  20           has any software write-protect mechanism you may want to review the
  21           code to make sure this driver won't turn it on by accident.
  22
  23           If you use this with an SMBus adapter instead of an I2C adapter,
  24           full functionality is not available.  Only smaller devices are
  25           supported (24c16 and below, max 4 kByte).
  26
  27           This driver can also be built as a module.  If so, the module
  28           will be called at24.

  30 config EEPROM_AT25
  31         tristate "SPI EEPROMs from most vendors"
  32         depends on SPI && SYSFS
  33         help
  34           Enable this driver to get read/write support to most SPI EEPROMs,
  35           after you configure the board init code to know about each eeprom
  36           on your target board.
  37
  38           This driver can also be built as a module.  If so, the module
  39           will be called at25.

  42         tristate "Old I2C EEPROM reader"
  43         depends on I2C && SYSFS
  44         help
  45           If you say yes here you get read-only access to the EEPROM data
  46           available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
  47           EEPROMs could theoretically be available on other devices as well.
  48
  49           This driver can also be built as a module.  If so, the module
  50           will be called eeprom.

  53         tristate "Maxim MAX6874/5 power supply supervisor"
  54         depends on I2C
  55         help
  56           If you say yes here you get read-only support for the user EEPROM of
  57           the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
  58           sequencer/supervisor.
  59
  60           All other features of this chip should be accessed via i2c-dev.
  61
  62           This driver can also be built as a module.  If so, the module
  63           will be called max6875.

  69           This is a driver for the EEPROM chipsets 93c46 and 93c66.
  70           The driver supports both read as well as write commands.
  71
  72           If unsure, say N.

  77         help
  78           Driver for the microwire EEPROM chipsets 93xx46x. The driver
  79           supports both read and write commands and also the command to
  80           erase the whole EEPROM.
  81
  82           This driver can also be built as a module.  If so, the module
  83           will be called eeprom_93xx46.

  90         help
  91           This option enables access to display configuration EEPROMs
  92           on digsy_mtc board. You have to additionally select Microwire
  93           EEPROM 93XX46 driver. sysfs entries will be created for that
  94           EEPROM allowing to read/write the configuration data or to
  95           erase the whole EEPROM.
