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.
