We will need to update the DTSI in a seperate patch as well.

Commit message could be better:

"Add support for watchdog device found in MT8192 SoC." for example.

I don't understand your comment. This patch modifies the binding. The link you
provide is from an older version of the series (which is called v2 as well...)

So repeating myself: if you are updating the binding descritpion you will have
to update the dtsi as well as otherwise the binding and the dtsi are out of sync.

Regards,
Matthias
