I made up some names - "FWCF" for the node name, and "FWCF0001" for _HID; no idea whether that's appropriate, or how else I should figure out what to use instead... Also, using scope "\\_SB", based on where fw_cfg shows up in the output of "info qtree". Again, if that's wrong, please point me in the right direction. Re. 3/3 (also mentioned after the commit blurb in the patch itself), I noticed none of the other DSDT entries contain a _STA field, wondering why it would (not) make sense to include that, same as on the PC. TIA for any feedback, comments, reviews, etc. --Gabriel Gabriel L.
