The watchdog driver compatible is "dlg,da9062-watchdog" and not
"dlg,da9062-wdt". Therefore the mfd-core can't populate the of_node and
fwnode. As result the watchdog driver can't parse the devicetree.

I do agree there's a mismatch between the documentation and the MFD code.
So in your DT are you specifying 'dlg,da9062-watchdog' and not 'dlg,da9062-wdt'
hence the issue? Are there any existing users who are using 'dlg,da9062-wdt' in
their DT instead?

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.

Ok, no problem. Just wanted to be clear. In which case:
