  5. help
  6. Enable this driver to get read/write support to most I2C EEPROMs,
  7. after you configure the driver to know about each EEPROM on
  8. your target board. Use these generic chip names, instead of
  9. vendor-specific ones like at24c64 or 24lc02:
  10. 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
  11. 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
  12. Unless you like data loss puzzles, always be sure that any chip
  13. you configure as a 24c32 (32 kbit) or larger is NOT really a
  14. 24c16 (16 kbit) or smaller, and vice versa. Marking the chip
  15. as read-only won't help recover from this. Also, if your chip
  16. has any software write-protect mechanism you may want to review the
  17. code to make sure this driver won't turn it on by accident.
  18. If you use this with an SMBus adapter instead of an I2C adapter,
  19. full functionality is not available. Only smaller devices are
  20. supported (24c16 and below, max 4 kByte).
  21. This driver can also be built as a module. If so, the module
  22. will be called at24.
  23. config EEPROM_AT25
  24. tristate "SPI EEPROMs from most vendors"
  25. depends on SPI && SYSFS
  26. help
  27. Enable this driver to get read/write support to most SPI EEPROMs,
  28. after you configure the board init code to know about each eeprom
  29. on your target board.
  30. This driver can also be built as a module. If so, the module
  31. will be called at25.
  32. config EEPROM_LEGACY
  33. tristate "Old I2C EEPROM reader"
  34. depends on I2C && SYSFS
  35. help
  36. If you say yes here you get read-only access to the EEPROM data
  37. available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
  38. EEPROMs could theoretically be available on other devices as well.
  39. This driver can also be built as a module. If so, the module
  40. will be called eeprom.
  41. config EEPROM_MAX6875
  42. tristate "Maxim MAX6874/5 power supply supervisor"
  43. depends on I2C && EXPERIMENTAL
  44. help
  45. If you say yes here you get read-only support for the user EEPROM of
  46. the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
  47. sequencer/supervisor.
  48. All other features of this chip should be accessed via i2c-dev.
  49. This driver can also be built as a module. If so, the module
  50. will be called max6875.
  51. config EEPROM_93CX6
  52. tristate "EEPROM 93CX6 support"
  53. help
  54. This is a driver for the EEPROM chipsets 93c46 and 93c66.
  55. The driver supports both read as well as write commands.
  56. If unsure, say N.
  57. config EEPROM_93XX46
  58. tristate "Microwire EEPROM 93XX46 support"
  59. depends on SPI && SYSFS
  60. help
  61. Driver for the microwire EEPROM chipsets 93xx46x. The driver
  62. supports both read and write commands and also the command to
  63. erase the whole EEPROM.
  64. This driver can also be built as a module. If so, the module
  65. will be called eeprom_93xx46.
  66. If unsure, say N.
  67. config EEPROM_DIGSY_MTC_CFG
  68. bool "DigsyMTC display configuration EEPROMs device"
  69. depends on GPIO_MPC5200 && SPI_GPIO
  70. help
  71. This option enables access to display configuration EEPROMs
  72. on digsy_mtc board. You have to additionally select Microwire
  73. EEPROM 93XX46 driver. sysfs entries will be created for that
  74. EEPROM allowing to read/write the configuration data or to
  75. erase the whole EEPROM.
  76. If unsure, say N.
