Hi Krzysztof,

  Just want to clarify, I believe you previous concern about the
"children of simple-bus are supposed to have unit addresses" [3] isn't
really an issue any more.. but, please let me know if I'm wrong..


Hi Vivian,

  We'd like to push this series for v6.17, so I've queued it at
k1/dt-for-next branch of SpacemiT SoC tree [4] for now, FYI.

Thanks all
