The code to read those properties was originally added by commit 89128534f, specifically to support the device I am trying to fix, the Chromebook Pixel 2015. Admittedly, it's possible some other device came along and matched these property names since then, but I'm inclined to think we might be the only ones. > It'd be fine to add your new DT style properties but this > might break existing systems. That said, I agree it would be safer to use the idiomatic ACPI names, and then fall back to the DT style names if the idiomatic names fail. Does that sound reasonable? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
