As you are adding new sysfs files here, is there a follow-on patch for
Documentation/ABI/ updates?
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.
