depends on [31mCONFIG_I2C[0m && [31mCONFIG_SYSFS[0m
select [31mCONFIG_NVMEM[0m
help
Enable this driver to get read/write support to most [31mCONFIG_I2C[0m EEPROMs
and compatible devices like FRAMs, SRAMs, ROMs etc. After you
configure the driver to know about each chip on your target
board. Use these generic chip names, instead of vendor-specific
ones like at24c64, 24lc02 or fm24c04:
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 [31mCONFIG_I2C[0m 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.
config [31mCONFIG_EEPROM_AT25[0m
tristate "SPI EEPROMs from most vendors"
depends on [31mCONFIG_SPI[0m && [31mCONFIG_SYSFS[0m
select [31mCONFIG_NVMEM[0m
help
Enable this driver to get read/write support to most [31mCONFIG_SPI[0m EEPROMs,
after you configure the board init code to know about each eeprom
on your target board.
This driver can also be built as a module. If so, the module
will be called at25.
config [31mCONFIG_EEPROM_LEGACY[0m
tristate "Old I2C EEPROM reader"
depends on [31mCONFIG_I2C[0m && [31mCONFIG_SYSFS[0m
help
If you say yes here you get read-only access to the EEPROM data
available on modern memory DIMMs and Sony Vaio laptops via [31mCONFIG_I2C[0m. Such
EEPROMs could theoretically be available on other devices as well.
This driver can also be built as a module. If so, the module
will be called eeprom.
config [31mCONFIG_EEPROM_MAX6875[0m
tristate "Maxim MAX6874/5 power supply supervisor"
depends on [31mCONFIG_I2C[0m
help
If you say yes here you get read-only support for the user EEPROM of
the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
sequencer/supervisor.
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
will be called max6875.
config [31mCONFIG_EEPROM_93CX6[0m
tristate "EEPROM 93CX6 support"
help
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.
config [31mCONFIG_EEPROM_93XX46[0m
tristate "Microwire EEPROM 93XX46 support"
depends on [31mCONFIG_SPI[0m && [31mCONFIG_SYSFS[0m
select [31mCONFIG_REGMAP[0m
select [31mCONFIG_NVMEM[0m
help
Driver for the microwire EEPROM chipsets 93xx46x. The driver
supports both read and write commands and also the command to
erase the whole EEPROM.
This driver can also be built as a module. If so, the module
will be called eeprom_93xx46.
If unsure, say N.
config [31mCONFIG_EEPROM_DIGSY_MTC_CFG[0m
bool "DigsyMTC display configuration EEPROMs device"
depends on [31mCONFIG_GPIO_MPC5200[0m && [31mCONFIG_SPI_GPIO[0m
help
This option enables access to display configuration EEPROMs
on digsy_mtc board. You have to additionally select Microwire
EEPROM 93XX46 driver. sysfs entries will be created for that
EEPROM allowing to read/write the configuration data or to
erase the whole EEPROM.
If unsure, say N.
