Thanks, I'm giving this a try, and get errors like:

      DTC     arch/arm/boot/dts/emev2-kzm9d.dt.yaml
    FATAL ERROR: No markers present in property 'cpu0' value

and

      DTC     arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dt.yaml
    FATAL ERROR: No markers present in property 'audio_clk_a' value

Do you have a clue?
Thanks!
