Yes that's the plan. The original patches for sysfs were submitted as an RFC: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-May/148699.html Most of the sysfs entries would mirror the value of _DSD properties, but that's still very useful to check platform integration issues. Some of the DSDT blocks are overwritten at run-time depending on BIOS menu selections, so it's impossible to figure out what the firmware exposes to the OS just by looking at the DSDT contents extracted with acpica tools.
