[PATCH v4 0/2] Add support for NXP LPC18xx Watchdog timer

[Ariel D'Alessandro]

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

Patchset is based on tag next-20150624 of the linux-next repository.
It has been successfully tested on a Hitex LPC4350 Evaluation Board and
on a CIAA NXP LPC4337 Board.

Changes since v3:
* Changed default timeout to 30.
* Minor changes.

Changes since v2:
* Changed config tristate to "LPC18xx/43xx".
* Added COMPILE_TEST as a dependency.
* Replaced raw_local_irq* calls by spinlock.
* Changed dt compatible string to "nxp,lpc1850-wwdt".

Changes since v1:
* Dropped "Windowed" term in Watchdog's name.
* Changed default timeout value from 1 to 5 because it was too tight.
* Fixed module remove function, since it was keeping the timer enabled. Warning
  message was added.
* Changed dt compatible string to "nxp,lpc1850-wdt".
* Renamed clocks matching most of the other lpc18xx drivers.
