[PATCH v3 00/15] Armada 370/XP watchdog support

[Ezequiel Garcia]

Third patchset to extend Orion watchdog driver adding support for
Armada 370/XP SoC. This consists on a small incremental series.

Please take a look at the previous version and the discussion raised:
http://www.spinics.net/lists/arm-kernel/msg302104.html

Changes from v2:

 * Add proper error checking on clk_prepare_enable() and return
   PTR_ERR instead of ENODEV. Suggested by Fabio Estevam.

 * After the usage of the atomic I/O and considering the watchdog core
   does its own serialization, the driver's spinlock was completely
   redundant and was removed. Also suggested by Fabio.

 * Instead of making the driver dependent on PLAT_ORION, added a dependency
   to ARCH_MVEBU. This was proposed by Sebastian and Andrew, given
   we're working on PLAT_ORION removal.

This series is based on v3.13-rc8 and has been tested on:

 * Marvell's Armada XP GP board
