We understand that ;-) What Jernej meant was that the DTS patches at the end depend on patch 01/10, which adds to the PHY binding doc. I am not sure if Vinod's suggestion was about splitting off 01/10, 03/10, and 10/10, or just the two latter which touch the driver. I can split off 03/10 and 10/10, rebased on top of linux-phy.git/next, and send that to Vinod. Then I would keep 01/10 in a respin of this series here, to satisfy the dependency of the later DTS patches, and Vinod can pick that one patch from there? Cheers, Andre

There is no hard dependency of DTS on bindings. You can split these (and some maintainers prefer that way) and in DTS patches just provide the link to the bindings, saying it is in progress. The bindings should be however kept with driver changes as it goes the same way. Best regards, Krzysztof

I would think that the DT bits - bindings first, then DTS files using it - should be bundled. This is how I imagine the future(TM), where DTs and bindings live outside the kernel repo. > The bindings should be however kept with driver changes as it goes the > same way. I understand that the bindings describe the contract the driver acts on, but going forward I think driver changes would need to come later, then (since they will live in a separate repo at some day)? Maybe pointing to the binding changes in progress? So with a separate repo we would actually need to upstream just the bindings first, then could push driver changes and .dts files independently? And for now it looks like we are stuck with putting everything in one series, to make both checkpatch and dtbs_check happy. Cheers, Andre

The check will be broken anyway because binding goes via driver subsystem and DTS goes via arm-soc.

You should rather make maintainers happy :) and here one asked to split. Best regards, Krzysztof

Well, he asked to split off the USB PHY patches from the rest of the series, since there is some conflict with the recently merged H616 USB PHY patches. It is still unclear to me whether this split includes the binding patch, or just the two patches touching the actual code. Cheers, Andre.

That mean split off USB phy and binding patches from rest and send for review DTS or anything else should not be part of that
