Pull watchdog changes from Wim Van Sebroeck: - conversion of iTCO_wdt and orion_wdt to the generic watchdog API - uses module_platform_driver() for s3c2410_wdt - Adds support for Jetway JNF99 Motherboard - various fixes * git://www.linux-watchdog.org/linux-watchdog: watchdog: orion_wdt: Convert driver to watchdog core watchdog: s3c2410_wdt: Use module_platform_driver() watchdog: sch311x_wdt: Fix Polarity when starting watchdog Watchdog: OMAP: Fix the runtime pm code to avoid module getting stuck intransition state. watchdog: ie6xx_wdt: section mismatch in ie6xx_wdt_probe() watchdog: bcm63xx_wdt: fix driver section mismatch watchdog: iTCO_wdt.c: convert to watchdog core char/ipmi: remove local ioctl defines replaced by generic ones watchdog: xilinx: Read clock frequency directly from DT node watchdog: coh901327_wdt: use clk_prepare/unprepare watchdog: f71808e_wdt: Add support for Jetway JNF99 motherboard
