This patch series adds support for NXP LPC18xx EEPROM memory found in
NXP LPC SoCs family, which includes LPC18xx/LPC43xx. Other SoCs in
that family may share the same watchdog hardware.

This patchset is based on tag next-20151013 of the linux-next
repository. It has been successfully tested on a LPC4337 CIAA-NXP

EEPROM notes:

EEPROM size is 16384 bytes and it can be entirely read and 
written/erased with 1 word (4 bytes) granularity. The last page
(128 bytes) contains the EEPROM initialization data and is not writable.

Erase/program time is less than 3ms. The EEPROM device requires a
~1500 kHz clock (min 800 kHz, max 1600 kHz) that is generated dividing
the system bus clock by the division factor, contained in the divider
register (minus 1 encoded).
