| 20 | help |
| 21 | Enable this driver to get read/write support to most I2C EEPROMs, |
| 22 | after you configure the driver to know about each EEPROM on |
| 23 | your target board. Use these generic chip names, instead of |
| 24 | vendor-specific ones like at24c64 or 24lc02: |
| 25 | |
| 26 | 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08, |
| 27 | 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024 |
| 28 | |
| 29 | Unless you like data loss puzzles, always be sure that any chip |
| 30 | you configure as a 24c32 (32 kbit) or larger is NOT really a |
| 31 | 24c16 (16 kbit) or smaller, and vice versa. Marking the chip |
| 32 | as read-only won't help recover from this. Also, if your chip |
| 33 | has any software write-protect mechanism you may want to review the |
| 34 | code to make sure this driver won't turn it on by accident. |
| 35 | |
| 36 | If you use this with an SMBus adapter instead of an I2C adapter, |
| 37 | full functionality is not available. Only smaller devices are |
| 38 | supported (24c16 and below, max 4 kByte). |
| 39 | |
| 40 | This driver can also be built as a module. If so, the module |
| 41 | will be called at24. |
