- menu "EEPROM support"
- config EEPROM_AT24
- tristate "I2C EEPROMs / RAMs / ROMs from most vendors"
- depends on I2C && SYSFS
- select REGMAP
- select NVMEM
- help
- Enable this driver to get read/write support to most I2C 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 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.
- config EEPROM_AT25
- tristate "SPI EEPROMs from most vendors"
- depends on SPI && SYSFS
- select REGMAP
- select NVMEM
- help
- Enable this driver to get read/write support to most SPI 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 EEPROM_LEGACY
- tristate "Old I2C EEPROM reader"
- depends on I2C && SYSFS
- 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 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
- will be called eeprom.
- config EEPROM_MAX6875
- tristate "Maxim MAX6874/5 power supply supervisor"
- depends on I2C
- 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 EEPROM_93CX6
- 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 EEPROM_93XX46
- tristate "Microwire EEPROM 93XX46 support"
- depends on SPI && SYSFS
- select REGMAP
- select NVMEM
- 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 EEPROM_DIGSY_MTC_CFG
- bool "DigsyMTC display configuration EEPROMs device"
- depends on GPIO_MPC5200 && SPI_GPIO
- 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.
