3config EEPROM_AT24
4	tristate "I2C EEPROMs from most vendors"
5	depends on I2C && SYSFS
6	help
7	  Enable this driver to get read/write support to most I2C EEPROMs,
8	  after you configure the driver to know about each EEPROM on
9	  your target board.  Use these generic chip names, instead of
10	  vendor-specific ones like at24c64 or 24lc02:
11
12	     24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
13	     24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
14
15	  Unless you like data loss puzzles, always be sure that any chip
16	  you configure as a 24c32 (32 kbit) or larger is NOT really a
17	  24c16 (16 kbit) or smaller, and vice versa. Marking the chip
18	  as read-only won't help recover from this. Also, if your chip
19	  has any software write-protect mechanism you may want to review the
20	  code to make sure this driver won't turn it on by accident.
21
22	  If you use this with an SMBus adapter instead of an I2C adapter,
23	  full functionality is not available.  Only smaller devices are
24	  supported (24c16 and below, max 4 kByte).
25
26	  This driver can also be built as a module.  If so, the module
27	  will be called at24.
28
29config EEPROM_AT25
30	tristate "SPI EEPROMs from most vendors"
31	depends on SPI && SYSFS
32	help
33	  Enable this driver to get read/write support to most SPI EEPROMs,
34	  after you configure the board init code to know about each eeprom
35	  on your target board.
36
37	  This driver can also be built as a module.  If so, the module
38	  will be called at25.
39
40config EEPROM_LEGACY
41	tristate "Old I2C EEPROM reader"
42	depends on I2C && SYSFS
43	help
44	  If you say yes here you get read-only access to the EEPROM data
45	  available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
46	  EEPROMs could theoretically be available on other devices as well.
47
48	  This driver can also be built as a module.  If so, the module
49	  will be called eeprom.
50
51config EEPROM_MAX6875
52	tristate "Maxim MAX6874/5 power supply supervisor"
53	depends on I2C && EXPERIMENTAL
54	help
55	  If you say yes here you get read-only support for the user EEPROM of
56	  the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
57	  sequencer/supervisor.
58
59	  All other features of this chip should be accessed via i2c-dev.
60
61	  This driver can also be built as a module.  If so, the module
62	  will be called max6875.

64
65config EEPROM_93CX6
66	tristate "EEPROM 93CX6 support"
67	help
68	  This is a driver for the EEPROM chipsets 93c46 and 93c66.
69	  The driver supports both read as well as write commands.
70
71	  If unsure, say N.
72
73config EEPROM_93XX46
74	tristate "Microwire EEPROM 93XX46 support"
75	depends on SPI && SYSFS
76	help
77	  Driver for the microwire EEPROM chipsets 93xx46x. The driver
78	  supports both read and write commands and also the command to
79	  erase the whole EEPROM.
80
81	  This driver can also be built as a module.  If so, the module
82	  will be called eeprom_93xx46.
83
84	  If unsure, say N.
85
86config EEPROM_DIGSY_MTC_CFG
87	bool "DigsyMTC display configuration EEPROMs device"
88	depends on GPIO_MPC5200 && SPI_GPIO
89	help
90	  This option enables access to display configuration EEPROMs
91	  on digsy_mtc board. You have to additionally select Microwire
92	  EEPROM 93XX46 driver. sysfs entries will be created for that
93	  EEPROM allowing to read/write the configuration data or to
94	  erase the whole EEPROM.
95
96	  If unsure, say N.
