Can you please mention in the commit message or subject line that this
includes the SoC .dtsi? Or maybe even split this out into a separate patch?

And is there any reason you didn't copy the official Linux DT version?
Or is that one here just an older copy of that?
Anyway, please use the most recent version of the .dtsi, so we can use
that directly to pass on to the kernel.

Thanks!
Andre.
