Pull watchdog updates from Wim Van Sebroeck:
 "This includes some fixes and code improvements (like
  clk_prepare_enable and clk_disable_unprepare), conversion from the
  omap_wdt and twl4030_wdt drivers to the watchdog framework, addition
  of the SB8x0 chipset support and the DA9055 Watchdog driver and some
  OF support for the davinci_wdt driver."
