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.

Lastly, the old memory accessor mechanism has been replaced with the
nvmem equivalent.

v7:
 Added more acked-by
 Added tested-by for patch #7
 Rebased onto current misc-char/misc-char-next.

Andrew Lunn (7):
  nvmem: Add flag to export NVMEM to root only
  nvmem: Add backwards compatibility support for older EEPROM drivers.
  eeprom: at24: extend driver to plug into the NVMEM framework
  eeprom: at25: Remove in kernel API for accessing the EEPROM
  eeprom: at25: extend driver to plug into the NVMEM framework
  eeprom: 93xx46: extend driver to plug into the NVMEM framework
  misc: at24: replace memory_accessor with nvmem_device_read
