Use these generic chip names, instead of vendor-specific 13 ones like at24c64, 24lc02 or fm24c04: 14 15 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08, 16 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024 17 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. 31 32config EEPROM_AT25 33 tristate "SPI EEPROMs from most vendors" 34 depends on SPI && SYSFS 35 select NVMEM 36 help 37 Enable this driver to get read/write support to most SPI EEPROMs, 38 after you configure the board init code to know about each eeprom 39 on your target board. 40 41 This driver can also be built as a module. If so, the module 42 will be called at25. 43 44config EEPROM_LEGACY 45 tristate "Old I2C EEPROM reader" 46 depends on I2C && SYSFS 47 help 48 If you say yes here you get read-only access to the EEPROM data 49 available on modern memory DIMMs and Sony Vaio laptops via I2C. Such 50 EEPROMs could theoretically be available on other devices as well. 51 52 This driver can also be built as a module. If so, the module 53 will be called eeprom. 54 55config EEPROM_MAX6875 56 tristate "Maxim MAX6874/5 power supply supervisor" 57 depends on I2C 58 help 59 If you say yes here you get read-only support for the user EEPROM of 60 the Maxim MAX6874/5 EEPROM-programmable, quad power-supply 61 sequencer/supervisor. 62 63 All other features of this chip should be accessed via i2c-dev. 64 65 This driver can also be built as a module. If so, the module 66 will be called max6875. 67 68 69config EEPROM_93CX6 70 tristate "EEPROM 93CX6 support" 71 help 72 This is a driver for the EEPROM chipsets 93c46 and 93c66. 73 The driver supports both read as well as write commands. 74 75 If unsure, say N. 76 77config EEPROM_93XX46 78 tristate "Microwire EEPROM 93XX46 support" 79 depends on SPI && SYSFS 80 select REGMAP 81 select NVMEM 82 help 83 Driver for the microwire EEPROM chipsets 93xx46x. The driver 84 supports both read and write commands and also the command to 85 erase the whole EEPROM. 86 87 This driver can also be built as a module. If so, the module 88 will be called eeprom_93xx46. 89 90 If unsure, say N. 91 92config EEPROM_DIGSY_MTC_CFG 93 bool "DigsyMTC display configuration EEPROMs device" 94 depends on GPIO_MPC5200 && SPI_GPIO 95 help 96 This option enables access to display configuration EEPROMs 97 on digsy_mtc board. You have to additionally select Microwire 98 EEPROM 93XX46 driver. sysfs entries will be created for that 99 EEPROM allowing to read/write the configuration data or to 100 erase the whole EEPROM. 101 102 If unsure, say N. 103 104config EEPROM_IDT_89HPESX 105 tristate "IDT 89HPESx PCIe-swtiches EEPROM / CSR support" 106 depends on I2C && SYSFS 107 help 108 Enable this driver to get read/write access to EEPROM / CSRs 109 over IDT PCIe-swtich i2c-slave interface. 110 111 This driver can also be built as a module.
