Thanks for an update!

I did review more thoughtfully the series and realized that you can
avoid that P2SB thingy and may the approach be much cleaner if you
register the real GPIO driver and convert your LEDs to be a GPIO LEDs.
Then you won't need any custom code for it (except some board file, or
what would be better to file _DSD in your ACPI tables.
