I'll sound like a broken record, but:

is there anyone in the world that is actively benefiting from this failed
experiment of using the ACPI tables that were shipped with these SoCs?

There are so so so many shortcomings associated with it due to how Windows
drivers on these platforms know waaaay too much and largely use ACPI to
"bind driver x" and I simply think it doesn't make sense to continue
carrying this code forward given little use and no testing.
