Lars Poeschel81e34f92012-12-05 10:43:07 +01007 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:
Wolfram Sang5195e502009-01-26 21:19:53 +010012
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.

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.

57 the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
58 sequencer/supervisor.

60 All other features of this chip should be accessed via i2c-dev.

79 supports both read and write commands and also the command to
80 erase the whole EEPROM.

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.
