5 tristate "I2C EEPROMs / RAMs / ROMs from most vendors"
6 depends on I2C && SYSFS
11 Enable this driver to get read/write support to most I2C EEPROMs
12 and compatible devices like FRAMs, SRAMs, ROMs etc. After you
13 configure the driver to know about each chip on your target
14 board. Use these generic chip names, instead of vendor-specific
15 ones like at24c64, 24lc02 or fm24c04:
17 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
18 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024, 24c2048
20 Unless you like data loss puzzles, always be sure that any chip
21 you configure as a 24c32 (32 kbit) or larger is NOT really a
22 24c16 (16 kbit) or smaller, and vice versa. Marking the chip
23 as read-only won't help recover from this. Also, if your chip
24 has any software write-protect mechanism you may want to review the
25 code to make sure this driver won't turn it on by accident.
27 If you use this with an SMBus adapter instead of an I2C adapter,
28 full functionality is not available. Only smaller devices are
29 supported (24c16 and below, max 4 kByte).
31 This driver can also be built as a module. If so, the module
35 tristate "SPI EEPROMs from most vendors"
36 depends on SPI && SYSFS
40 Enable this driver to get read/write support to most SPI EEPROMs,
41 after you configure the board init code to know about each eeprom
44 This driver can also be built as a module. If so, the module
48 tristate "Old I2C EEPROM reader (DEPRECATED)"
49 depends on I2C && SYSFS
51 If you say yes here you get read-only access to the EEPROM data
52 available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
53 EEPROMs could theoretically be available on other devices as well.
55 This driver is deprecated and will be removed soon, please use the
56 better at24 driver instead.
58 This driver can also be built as a module. If so, the module
59 will be called eeprom.
62 tristate "Maxim MAX6874/5 power supply supervisor"
65 If you say yes here you get read-only support for the user EEPROM of
66 the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
69 All other features of this chip should be accessed via i2c-dev.
71 This driver can also be built as a module. If so, the module
72 will be called max6875.
76 tristate "EEPROM 93CX6 support"
78 This is a driver for the EEPROM chipsets 93c46 and 93c66.
79 The driver supports both read as well as write commands.
84 tristate "Microwire EEPROM 93XX46 support"
85 depends on SPI && SYSFS
90 Driver for the microwire EEPROM chipsets 93xx46x. The driver
91 supports both read and write commands and also the command to
92 erase the whole EEPROM.
94 This driver can also be built as a module. If so, the module
95 will be called eeprom_93xx46.
99 config EEPROM_DIGSY_MTC_CFG
100 bool "DigsyMTC display configuration EEPROMs device"
101 depends on GPIO_MPC5200 && SPI_GPIO
103 This option enables access to display configuration EEPROMs
104 on digsy_mtc board. You have to additionally select Microwire
105 EEPROM 93XX46 driver. sysfs entries will be created for that
106 EEPROM allowing to read/write the configuration data or to
107 erase the whole EEPROM.
111 config EEPROM_IDT_89HPESX
112 tristate "IDT 89HPESx PCIe-swtiches EEPROM / CSR support"
113 depends on I2C && SYSFS
115 Enable this driver to get read/write access to EEPROM / CSRs
116 over IDT PCIe-swtich i2c-slave interface.
118 This driver can also be built as a module. If so, the module
119 will be called idt_89hpesx.
122 tristate "SPD EEPROMs on DDR4 memory modules"
123 depends on I2C && SYSFS
125 Enable this driver to get read support to SPD EEPROMs following
126 the JEDEC EE1004 standard. These are typically found on DDR4
127 SDRAM memory modules.
129 This driver can also be built as a module. If so, the module
130 will be called ee1004.
