Thanks a lot for your efforts!

To me it looks like the long time anticipated replacement of [persistent]
SYSFS userspace API finally landed and one can start thinking about phasing
out the API declared obsolete in Linux v4.8 ;-)

I've compiled gpio-manager and gpiocli for TI am625 (arm64) and tested on
some HW one may compare to Beagle Play.

To me it looks solid, no problems whatsoever noticed up to now, even though
some non-obvious limitations do exist
("gpiocli request: all requested lines must belong to the same chip"), but
this probably can either be justified in documentation or improved even
after merging.

Will be happy to provide Tested-by: as soon as you send the series for
merging!
