9 | Enable this driver to get read/write support to most I2C EEPROMs |
10 | and compatible devices like FRAMs, SRAMs, ROMs etc. After you | |
11 | configure the driver to know about each chip on your target | |
12 | board. Use these generic chip names, instead of vendor-specific | |
13 | ones like at24c64, 24lc02 or fm24c04: | |

18 | Unless you like data loss puzzles, always be sure that any chip | |
19 | you configure as a 24c32 (32 kbit) or larger is NOT really a | |
20 | 24c16 (16 kbit) or smaller, and vice versa. Marking the chip | |
21 | as read-only won't help recover from this. Also, if your chip | |
22 | has any software write-protect mechanism you may want to review the | |
23 | code to make sure this driver won't turn it on by accident. | |
24 | ||
25 | If you use this with an SMBus adapter instead of an I2C adapter, | |
26 | full functionality is not available. Only smaller devices are | |
27 | supported (24c16 and below, max 4 kByte). | |
28 | ||
29 | This driver can also be built as a module. If so, the module | |
30 | will be called at24. | |

36 | Enable this driver to get read/write support to most SPI EEPROMs, | |

38 | on your target board. | |

46 | help |
47 | If you say yes here you get read-only access to the EEPROM data | |
48 | available on modern memory DIMMs and Sony Vaio laptops via I2C. Such | |
49 | EEPROMs could theoretically be available on other devices as well. | |
50 | ||
51 | This driver can also be built as a module. If so, the module | |
52 | will be called eeprom. | |

57 | help |
58 | If you say yes here you get read-only support for the user EEPROM of | |
59 | the Maxim MAX6874/5 EEPROM-programmable, quad power-supply | |
60 | sequencer/supervisor. | |
61 | ||
62 | All other features of this chip should be accessed via i2c-dev. | |

71 | This is a driver for the EEPROM chipsets 93c46 and 93c66. | |
72 | The driver supports both read as well as write commands. | |

80 | Driver for the microwire EEPROM chipsets 93xx46x. The driver | |
81 | supports both read and write commands and also the command to | |

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