Awesome! I think this series would benefit from a cover letter
explaining what features are working, and perhaps saying something
about other patches that will be sent separately (if any). The as3668
led driver and bindings for example has not been merged, right? Adding
the lore link in a cover letter would therefore help reviewers.
One nitpick below that I happened to notice.
