Pull first set of watchdog updates from Wim Van Sebroeck:
 "This pull contains:

   - The removal of ixp2000_wdt
   - The addition of ie6xx_wdt
   - Some documentation fixes
   - Small fixes and improvements

  (Note: Part 2 will contain generic watchdog core changes + conversion
  of some more drivers)"

* NXP PNX watchdog timer



Required properties:

- compatible: must be "nxp,pnx4008-wdt"

- reg: physical base address of the controller and length of memory mapped

  region.



Example:



	watchdog@4003C000 {

		compatible = "nxp,pnx4008-wdt";

		reg = <0x4003C000 0x1000>;

	};
