This patch set converts the old EEPROM drivers in driver/misc/eeprom to use the NVMEM framework. These drivers export there content in /sys as read only to root, since the EEPROM may contain sensitive information. So the first patch adds a flag so the NVMEM framework will create its file in /sys as root read only.
To keep backwards compatibility with these older drivers, the contents of the EEPROM must be exports in sysfs in a file called eeprom in the devices node in sys, where as the NVMEM places them under class/nvmem. So add this optional backwards compatible to the framework, again using a flag. Then convert the at24, at25 and 93xx46 by adding regmap support, removing each drivers own /sys code and registering with the NVMEM framework. AT24 and 93xx46 has been boot tested, at25 compile tested only. v2: nvmem_register() now supports a backwards compatible flag, and the Kconfig option has been removed.
