Almost there :) All I need is an ack from DT maintainers for this patch. DT maintainers: I think this is the best option and I can't think of any other solution so I would prefer to take this approach to our ath.git tree if it's ok for you. IIRC someone suggested testing for firmware version string but I suspect that has the same problem as the firmware-N.bin approach: ath10k gets the firmware version too late. And besides it's difficult to maintain such a list in ath10k, it would always need kernel updates when there's a new firmware etc.

Because of the multiple trees involved (ath-next -> wireless-next -> net-next -> linus) we need to have ath.git pull request ready well before the merge window opens and these commits missed the last pull request. Yes, we are slow :)

(To me, it fixed broken behavior in the FW, but I understand if the nature of the changes require a more prudent approach. Though they are disabled for everyone by default.) Regards

So the path for ath10k/ath11k/ath12k fixes to current -rc release is: ath-current -> wireless -> net -> linus For new features going to the next release: ath-next -> wireless-next -> net-next -> (in merge window) linus To reduce conflicts between trees most of the patches I apply go to -next, I usually take only important regression fixes to -current. In this case I didn't even consider taking the patches to -current as there were changes in DT and I just assumed this is for -next. If you considered otherwise I didn't realise it, sorry about that. In future, if you think a patch should go to -current please mention it somewhere, preferably something like tagging it with "[PATCH wireless]" or "[PATCH ath-current]" etc. to document which tree it is for. Or just as a simple reply.
