3bd69ad077 driver: replace dev_request_mem_region with dev_request_mem_resource 
dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.

This patch has been generated with the following semantic patch:

62fe28cf0b watchdog: Give watchdogs a name 
This adds a dev and name member to struct watchdog which helps distinguishing
between different watchdogs. Also add some debugging aids.

5cef8a3670 ARM/MXS/i.MX28: recognize watchdog reset 
When a watchdog timeout is set in the linux kernel, the FORCE_UPDATE bit is set.
Use this to recognize a system reset that was triggered by the watchdog.
Since only the wdt part of the kernel driver sets this bit, this is a safe
distinguishing feature.

0c8b031ead ARM/MXS: add more ROM code related documentation 
Commit 17176c2e2b adds a test of a new RTC
register flag to distinguish a system reset and a wake up event. Shame on me,
I have forgotten to define the newly used flag yet.

While already here, I also try to document the other flags the RTC provides.

17176c2e2b ARM/MXS/i.MX28: distinguish POR and wake-up event correctly 
When the built-in RTC in the i.MX28 is programmed to wake-up the SoC, the RTC
reports two events: RST and WAKE. RST is okay in this case, because the PMIC
was really powered down. But the real event is the WAKE from the RTC and
should have precedence over the RST event. So, report the WAKE event for this
special case.
