watchdog: dw: Enable OF support for DW watchdog timer
watchdog: watchdog_core: Fix a trivial typo

2) patches that I am reviewing or are on my radar:
w83627hf-patches
Orion-patches
f81865_gpio.c
[PATCH V2 0/4] Add watchdog DT nodes and parse it to read PMU registers addresses (Exynos+s3c2410_wdt)

Hi Wim,

thanks a lot for getting this all done.

There is also
	http://patchwork.roeck-us.net/patch/503/
	Move and rename HP watchdog timer driver

[ Not sure if that is a good idea. For hwmon, I noticed that out-of-directory
  hwmon drivers are not reviewed by hwmon maintainers, often resulting in bad
  or even broken code ]

and
	http://patchwork.roeck-us.net/patch/264/
	watchdog: Sysfs interface for MEN A21 watchdog

[ It might make more sense to add common sysfs attributes to the
  watchdog code ]

Thanks,
Guenter

I had not reviewed on this one, as I think that such enhancements
should really start with a conversion to the watchdog infrastructure.
That is just my personal opinion, of course.

Thanks,
Guenter

No problem :-). Thanks also for your reviews and testing. It makes my life easier.

This patch will not go in. I agree with your statement: "If that is the case,
wouldn't it make more sense to have separate drivers, one per functionality,
plus an mfd driver to bind them all together ?". Especially because there is
practically no code re-usage...

I still have this patch in a seprate folder. So yes that one is also still on my radar.
But since I am not completely happy with some of the sysfs attribute-namings, and since
some of the code would be in the sysfs core part, I put the patch aside till after I
complete the sysfs code. (But I want to do the windond stuff first).

Kind regards,
Wim.

I think the enhancement might be worthwhile, but not in it's present form.
I agree that it would be nice to have the conversion also, but it's two seperate things for the moment..

Kind regards,
Wim.
