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. | |

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

60 | If you say yes here you get read-only support for the user EEPROM of | |
61 | the Maxim MAX6874/5 EEPROM-programmable, quad power-supply | |
62 | sequencer/supervisor. | |
63 | ||
64 | All other features of this chip should be accessed via i2c-dev. | |

97 | This option enables access to display configuration EEPROMs | |
98 | on digsy_mtc board. You have to additionally select Microwire | |
99 | EEPROM 93XX46 driver. sysfs entries will be created for that | |
