Pull watchdog fixes from Wim Van Sebroeck:
 - a null pointer dereference fix for omap_wdt
 - some clock related fixes for pnx4008
 - an underflow fix in wdt_set_timeout() for w83977f_wdt
 - restart fix for tegra wdt
 - Kconfig change to support Freescale Layerscape platforms
 - fix for stopping the mtk_wdt watchdog

* git://www.linux-watchdog.org/linux-watchdog:
  watchdog: mtk_wdt: Use MODE_KEY when stopping the watchdog
  watchdog: Add support for Freescale Layerscape platforms
  watchdog: tegra: Stop watchdog first if restarting
  watchdog: w83977f_wdt: underflow in wdt_set_timeout()
  watchdog: pnx4008: make global wdt_clk static
  watchdog: pnx4008: fix warnings caused by enabling unprepared clock
  watchdog: omap_wdt: fix null pointer dereference
