4d8b229d5e watchdog: Add 'action' and 'data' parameters to restart handler callback 
The 'action' (or restart mode) and data parameters may be used by restart
handlers, so they should be passed to the restart callback functions.

8773926d71 watchdog: mach-moxart: add restart handler 
mach-moxart lacks a separate register for reset; as a workaround,
add a function that can be hooked to arm_pm_restart.

e14538e0db watchdog: Add MOXA ART watchdog driver 
This patch adds a watchdog driver for the main hardware watchdog timer
found on MOXA ART SoCs.

The MOXA ART SoC provides one writable timer register, restarting
the hardware once it reaches zero. The register is auto decremented
every APB clock cycle.
