            : virtual keyboard is show when the tablet is undocked
            : and hidden when docked.
Can it be tested by looking at some logs?

This is from a different commit, isn’t it?

There is already:

1.  `src/mainboard/purism/librem_jsl/acpi/vbtn.asl`
2.  `src/ec/google/wilco/acpi/vbtn.asl`

Should it be at least named like this? Any possibilities to generalize the driver?
