Summary

This ACPI device exposed by the Chrome EC reports when a laptop-tablet convertible Chromebook (e.g., Google Pixelbook) is switched to tablet mode. Like on Linux, the reporting is via evdev:

-event3   SWITCH_TOGGLE     +3.27s      switch tablet-mode state 1
 event3   SWITCH_TOGGLE     +8.63s      switch tablet-mode state 0

though it would be possible to add other kinds notifications I guess.

@imp Is it possible to get this and acpi_ibm autoloaded with devmatch? Not sure if it would work with current structure or need additional code paths inside devmatch itself.

No help is needed? :) That's the Linux patch adding support for the generic standard PNP0C60 device. And this here is the FreeBSD patch adding support for the Google specific GOOG0006 device.

Can you integrate Google specific GOOG0006 device into acpi_button driver ?
