There seem to be many more violators of `#interrupt-cells = <1>;`, at
least on -next e6ada6df471f. It seems those are not intentionally
omitted in this patch? Searching for `interrupt-parent = <&mdss>;`
globally and evaluating `interrupts =` right next to it yields:

- Two more hits in both sdm845.dtsi and sm8250.dtsi;
- qcom-msm8974.dtsi;
- msm8996.dtsi;
- sdm630.dtsi;
- sdm660.dtsi.

And for the docs patch:
- mdp5.txt;
- And the recently added dpu-qcm2290.yaml, whose CI failure might have
exactly lead to this patch?

Would you mind cleaning these up in a v2, or otherwise explain and
forgive my ignorance for not seeing why these were not changed?

Thanks!

- Marijn
