[PATCH] i2c: nvmem: at24: Provide an EEPROM framework interface

For DT and in-kernel users there is no interface to the at24 EEPROMs so provide an NVMEM framework interface. This allows us to use AT24 based EEPROMs and reference them from within the DT tree. Signed-off-by: Pantelis Antoniou --- drivers/misc/eeprom/at24.c | 219
