Please keep along revisions the Reviewed-by/Acked-by/Tested-by from previous reviews like the one from https://lore.kernel.org/r/CAFBinCBN-QoA-e9JzfUq-Wc4Chu=x6cVoP2SYf=q-GrnLdLGKg@mail.gmail.com

And please CC devicetree at vger.kernel.org to have a proper review from the Rob Herring, without a proper review from Rob I can't take it.
