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. * git://www.linux-watchdog.org/linux-watchdog: (33 commits) watchdog: txx9wdt: fix timeout watchdog: Convert txx9wdt driver to watchdog framework watchdog: coh901327_wdt.c: fix timeout watchdog: coh901327: convert to use watchdog core watchdog: Add support for WDIOC_GETTIMELEFT IOCTL in watchdog core watchdog: ep93xx_wdt: timeout is an unsigned int value. watchdog: ep93xx_wdt: Fix timeout after conversion to watchdog core watchdog: Convert ep93xx driver to watchdog core watchdog: sp805: Use devm routines watchdog: sp805: replace readl/writel with lighter _relaxed variants watchdog: sp805: Fix documentation style comment watchdog: mpcore_wdt: Allow platform_get_irq() to fail watchdog: mpcore_wdt: Use devm routines watchdog: mpcore_wdt: Rename dev to pdev for pointing to struct platform_device watchdog: xen: don't clear is_active when xen_wdt_stop() failed watchdog: xen: don't unconditionally enable the watchdog during resume watchdog: fix compiler error for missing parenthesis watchdog: ep93xx_wdt.c: fix platform probe watchdog: ep93xx: Convert the watchdog driver into a platform device. watchdog: fix set_timeout operations ...
