Thanks! Do you happen to have time to check the other custom bindings in
SDM845 as well? I see two other differences there in addition to the

  1. "qcom,msm-geni-uart": Linux has an additional "qcom,geni-se-qup"
     node around that.

  2. The "qcom,pm8998-pwrkey" should be in an additional
     "qcom,pm8998-pon" container node and then called

     Also, in U-Boot the keys are modelled as GPIOs which is a bit
     strange (I don't think they can be set to output mode for example).
     But it might be fine to keep that in the -u-boot.dtsi part for now.

I would be happy to investigate and test the remaining DB410c-specific
parts (e.g. USB there). Cleaning up the DT differences has been on my
TODO list for quite some time but I never got to it, sadly...
