Yes the upstream available DT I'm currently using is:
arch/arm/boot/dts/imx6qdl-phytec-phycore-som.dtsi.

I grep the code and found no _upstream_ user of 'dlg,da9062-wdt' also
using this compatible would be a missmatch with the binding
documentation. So those DT's assuming a wrong binding. Therefore I fixed
it here and not within the watchdog driver.
