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.
