Well, my recent proposal to fix dtbscheck was the other way round: remove "ingenic,jz4780-otg" from jz4780.dtsi and leave it out here. > I'm not too sure, but since we already have a dedicated "ingenic, jz4780-otg", it seems "snps,dwc2" is redundant. As far as I see there is no driver specialization compatible to "ingenic,jz4780-otg". `grep ingenic,jz4780-otg *` only shows the .dtsi (and the new .yaml). So we need "snps,dwc2" to get any driver match and I thought the "ingenic,jz4780-otg" is redundant. But maintainers convinced me to keep it as a dummy compatible in the .dtsi for potential future specialization (which does not exist and seems not to be necessary). Unless I can convince them that this is never ever needed. Which is beyond my knowledge and almost everyone. So we can't remove the "snps,dwc2" here. Well, we can with more work elsewhere. You have to extend the dwc2_of_match_table to include all ingenic devices. Therefore we now know 3 potential solutions: a) remove "ingenic,jz4780-otg" from jz4780.dtsi (my proposal) b) add "ingenic,jz4780-otg" to dwc2.yaml together with "snps,dwc2" (your proposal + my suggestion here) c) add only "ingenic,jz4780-otg" to dwc2.yaml and extend the match table in drivers//usb/dwc2/params.c (new proposals) From consistency point of view I think variant b) is the right one. a) was rejected and c) only adds redundant code. I am open to anything as long as the dtbscheck doesn't complain any more. BR an thanks, Nikolaus

You are probably right, I forgot that the OTG driver only exists in my local repository and is not merged into the mainline. If we remove "snps,dwc2", the OTG of the JZ4780 in the current version will not work properly. I will send v3 tomorrow.

Ah, ok. Now I see. I was just focussed on this patch and related dtbscheck messages and did not read patch 2/2. Yes, looking at both, they are variant c). Sorry that I didn't see it earlier. As said: I am open to anything as long as the dtbscheck doesn't complain any more. BR and sorry for the confusion, Nikolaus

It looks like we need a [3/3] to remove "snps,dwc2", which not only solves the dtbscheck complaining problem, but also doesn't affect normal use after removing "snps,dwc2". > > As said: I am open to anything as long as the dtbscheck doesn't complain any more. > > BR and sorry for the confusion, > Nikolaus
