Required Properties:

• Compatibility : “marvell,orion-wdt”

      "marvell,armada-370-wdt"
      "marvell,armada-xp-wdt"
      "marvell,armada-375-wdt"
      "marvell,armada-380-wdt"
  

• reg : Should contain two entries: first one with the

      timer control address, second one with the
      rstout enable address.
  

For “marvell,armada-375-wdt” and “marvell,armada-380-wdt”:

• reg : A third entry is mandatory and should contain the

“marvell,armada-375-wdt”
“marvell,armada-380-wdt”:

• clocks : Must contain an entry for each entry in clock-names.
