Subject: [RESEND PATCH 0/3] watchdog: MAX63xx cleanup and platform settings

The first version of this patchset from January, 29 [1] got no feedback
from the maintainer. 1/4 [2] was applied to watchdog-next on May, 30
though. A concern about constants removal was raised in the preliminary
2/4 cleanup patch, the explanation has been added to the related commit
message.

Thus, resend the patchset. Below come the details about the changes:

The purpose of this patchset is to add a platform data structure for the
max63xx_wdt driver in order to setup the device in a platform code. This is
especially handy if the driver is built-in and/or the device registers
aren't memory mapped.

First, clean up the driver to help distinguish different device connections
and ease the introduction of new features. Then, add new platform settings
to support GPIO wired MAX63xx devices, and a different heartbeat.

Tested with a GPIO wired MAX6373 on an Atom platform, with a built-in
driver.
