5 tristate "I2C EEPROMs / RAMs / ROMs from most vendors"
6 depends on I2C && SYSFS
12 Enable this driver to get read/write support to most I2C EEPROMs
13 and compatible devices like FRAMs, SRAMs, ROMs etc. After you
14 configure the driver to know about each chip on your target
15 board. Use these generic chip names, instead of vendor-specific
16 ones like at24c64, 24lc02 or fm24c04:
18 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
19 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024, 24c2048
21 Unless you like data loss puzzles, always be sure that any chip
22 you configure as a 24c32 (32 kbit) or larger is NOT really a
23 24c16 (16 kbit) or smaller, and vice versa. Marking the chip
24 as read-only won't help recover from this. Also, if your chip
25 has any software write-protect mechanism you may want to review the
26 code to make sure this driver won't turn it on by accident.
28 If you use this with an SMBus adapter instead of an I2C adapter,
29 full functionality is not available. Only smaller devices are
30 supported (24c16 and below, max 4 kByte).
32 This driver can also be built as a module. If so, the module
36 tristate "SPI EEPROMs from most vendors"
37 depends on SPI && SYSFS
41 Enable this driver to get read/write support to most SPI EEPROMs,
42 after you configure the board init code to know about each eeprom
45 This driver can also be built as a module. If so, the module
49 tristate "Old I2C EEPROM reader (DEPRECATED)"
50 depends on I2C && SYSFS
52 If you say yes here you get read-only access to the EEPROM data
53 available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
54 EEPROMs could theoretically be available on other devices as well.
56 This driver is deprecated and will be removed soon, please use the
57 better at24 driver instead.
59 This driver can also be built as a module. If so, the module
60 will be called eeprom.
63 tristate "Maxim MAX6874/5 power supply supervisor"
66 If you say yes here you get read-only support for the user EEPROM of
67 the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
70 All other features of this chip should be accessed via i2c-dev.
72 This driver can also be built as a module. If so, the module
73 will be called max6875.
77 tristate "EEPROM 93CX6 support"
79 This is a driver for the EEPROM chipsets 93c46 and 93c66.
80 The driver supports both read as well as write commands.
85 tristate "Microwire EEPROM 93XX46 support"
86 depends on SPI && SYSFS
91 Driver for the microwire EEPROM chipsets 93xx46x. The driver
92 supports both read and write commands and also the command to
93 erase the whole EEPROM.
95 This driver can also be built as a module. If so, the module
96 will be called eeprom_93xx46.
100 config EEPROM_DIGSY_MTC_CFG
101 bool "DigsyMTC display configuration EEPROMs device"
102 depends on GPIO_MPC5200 && SPI_GPIO
104 This option enables access to display configuration EEPROMs
105 on digsy_mtc board. You have to additionally select Microwire
106 EEPROM 93XX46 driver. sysfs entries will be created for that
107 EEPROM allowing to read/write the configuration data or to
108 erase the whole EEPROM.
112 config EEPROM_IDT_89HPESX
113 tristate "IDT 89HPESx PCIe-swtiches EEPROM / CSR support"
114 depends on I2C && SYSFS
116 Enable this driver to get read/write access to EEPROM / CSRs
117 over IDT PCIe-swtich i2c-slave interface.
119 This driver can also be built as a module. If so, the module
120 will be called idt_89hpesx.
123 tristate "SPD EEPROMs on DDR4 memory modules"
124 depends on I2C && SYSFS
126 Enable this driver to get read support to SPD EEPROMs following
127 the JEDEC EE1004 standard. These are typically found on DDR4
128 SDRAM memory modules.
130 This driver can also be built as a module. If so, the module
131 will be called ee1004.
