Subject: [GIT PULL REQUEST] watchdog - v3.4 merge window
Hi Linus,
Please pull from 'master' branch of
git://www.linux-watchdog.org/linux-watchdog.git
This series contains:
* Removal of the Documentation/watchdog/00-INDEX file
* Fix boot status reporting for imx2_wdt
* clean-up sp805_wdt, pnx4008_wdt and mpcore_wdt
* convert printk in watchdog drivers to pr_ functions
* change nowayout module parameter to bool for every watchdog device
* conversion of jz4740_wdt, pnx4008_wdt, max63xx_wdt, softdog, ep93xx_wdt,
coh901327 and txx9wdt to new watchdog API
* Add support for the WDIOC_GETTIMELEFT ioctl call to the new watchdog API
* Change the new watchdog API so that the driver updates the timeout value
* two fixes for the xen_wdt driver
This pull will update the following files:

After the conversion of this driver to the watchdog core, I noticed that we
miss setting the initial timeout of the wdt device.
This results in a failure of the WDIOC_GETTIMEOUT ioctl call.

watchdog: watchdog_dev: Let the driver update the timeout field on set_timeout success
When a set_timeout operation succeeds this does not necessarily mean that
the exact timeout requested has been achieved, because the watchdog does not
necessarily have a 1 second resolution. So rather then have the core set
the timeout member of the watchdog_device struct to the exact requested
value, instead the driver should set it to the actually achieved timeout value.

watchdog: Convert jz4740_wdt driver to watchdog core
This patch converts jz4740_wdt driver to use watchdog core APIs.
Also use devm_* APIs to save a few error handling code.

watchdog: pnx4008: cleanup resource handling using managed devices
The resource handling in this driver was flaky: IO_ADDRESS instead of
ioremap (and no unmapping), an unneeded static resource, no central exit
path for error cases. Fix this by converting the driver to use managed
resources. Also use dev_*-messages instead of pr_* while we are here.

watchdog: make imx2_wdt report boot status correctly
Ioctl WDIOC_GETBOOTSTATUS is supposed to return some information
on why the system did (re)boot recently, value WDIOF_CARDRESET
being used to indicate watchdog induced reboot.
Up to now, imx2_wdt did not provide a value here, always returning
zero to indicate normal boot.
Do evaluate the IMX Watchdog Reset Status Register and
produce WDIOF_CARDRESET with WDIOC_GETBOOTSTATUS in case
of a watchdog induced reset.

watchdog: documentation: remove index-file
The 00-index file in the watchdog directory is, like many others,
outdated (conversion-howto is missing) and doesn't contain worthwhile
additional information. As it seems to be a maintenance burden without
much gain, simply remove it.
