This driver only reads the user EEPROM of that chip, so we can move it to the eeprom-directory in order to further clean up (and later remove) drivers/i2c/chips. The Kconfig text was updated to match the current functionality, dropping the meanwhile obsoleted parts. Defconfigs have been adapted.

|
|
Enable this driver to get read/write support to most I2C EEPROMs,
|
|
after you configure the driver to know about each EEPROM on
|
|
your target board. Use these generic chip names, instead of
|
|
vendor-specific ones like at24c64 or 24lc02:
|
|
|
|
24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
|
|
24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
|
|
|
|
Unless you like data loss puzzles, always be sure that any chip
|
|
you configure as a 24c32 (32 kbit) or larger is NOT really a
|
|
24c16 (16 kbit) or smaller, and vice versa. Marking the chip
|
|
as read-only won't help recover from this. Also, if your chip
|
|
has any software write-protect mechanism you may want to review the
|
|
code to make sure this driver won't turn it on by accident.
|
|
|
|
If you use this with an SMBus adapter instead of an I2C adapter,
|
|
full functionality is not available. Only smaller devices are
|
|
supported (24c16 and below, max 4 kByte).
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called at24.

If you say yes here you get read-only access to the EEPROM data
|
|
available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
|
|
EEPROMs could theoretically be available on other devices as well.
|

This driver can also be built as a module. If so, the module

|
|
the Maxim MAX6874/5 EEPROM-programmable, quad power-supply

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

This driver can also be built as a module. If so, the module

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