5 | Support for NVMEM(Non Volatile Memory) devices like EEPROM, EFUSES... | |
6 | ||
7 | This framework is designed to provide a generic interface to NVMEM | |
8 | from both the Linux Kernel and the userspace. | |
9 | ||
10 | This driver can also be built as a module. If so, the module | |
11 | will be called nvmem_core. | |
12 | ||
13 | If unsure, say no. | |
