Merge git://www.linux-watchdog.org/linux-watchdog

Pull watchdog updates from Wim Van Sebroeck:
 - 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

Fix up conflicts in ep93xx driver due to the same patches being merged
through separate branches.
