Yes, that's on purpose. We're temporarily disabling these nodes instead of reverting the series which should not have been merged. Once we have driver support, these properties will be updated again.

I think you're just being unreasonable here. If Bjorn could rebase his tree, he could simply drop these for now as sound support was clearly not ready. Since that isn't the case we need to at least try to be constructive and figure out a reasonable alternative. While "Linux isn't the only consumer" is a true statement, it really is not relevant just because there are some dts changes in Bjorn's tree which should not be there. Johan

But the DTS changes are in Bjorn branch and Bjorn and I discussed it and decided to disable them temporarily instead of reverting. Now you're asking me to figure out all the dependent driver and patch them individually.

Only that the drivers fail to probe in multiple ways, some which may require updating the bindings to address. There's also an indication that some further driver support is needed for proper speaker protection. That really should be in place before we enable this. Johan

Pretty often broken and not stable, so anyone using it accepts the risks. Using now linux-next argument for a change is not appropriate. The change should be reasonable regardless of users of linux-next. > >>> If Bjorn could rebase his tree, he could simply drop these for now as >>> sound support was clearly not ready.

I don't think there is anything needed to fix in bindings in incompatible way. I was working on them as well (for HDK8450) and I don't recall any issues. If you see anything specific, use specific arguments, because otherwise it is just FUD. > There's also an indication > that some further driver support is needed for proper speaker > protection. That really should be in place before we enable this. There is easy solution for this - drop the compatible from drivers. Or if driver is SC8280xp specific, mark it as BROKEN in Kconfig. Or fail the probe so it won't bother your system. Best regards, Krzysztof

Also note that these depend on q6prmcc which is in turn depends on remoteproc_adsp being enabled by the x13s dts. So keeping them disabled by default seems justified. Johan
