The commit message of the latter explains why the ABI was broken. However, the current devicetree files were not updated to the new ABI described in Documentation/devicetree/bindings/timer/ingenic,tcu.txt, so the watchdog driver would not probe. Fix this problem by updating the watchdog nodes to comply with the new ABI.
