my preferred fix would be:

 - add an imx35 compatible to all newer dtsi
 - update the driver to only write the wmcr on imx35 compatible devices
   adding only imx35.

Compared to Vladimir's change this undoes 5fe65ce7ccbb ("watchdog:
imx2_wdt: Disable power down counter on boot") on the newer generation
SoCs until their dtb is updated. 5fe65ce7ccbb fixed a problem in 2014
for these newer SoCs which wasn't urgent enough to be fixed earlier, so
I'd say this isn't a big problem and in return the drivers and device
trees stay simpler.

Best regards
Uwe
