Hi,

If you give me a hint, which tree or patchset should be tested, and
some hints what should be tested, I can try.

haven't written anything for apu1 yet (as I dont have one), but I wrote
the drivers for apu2/3/4.

My idea (which I never actually started on) was writing a separate gpio
driver (not LED) for the old Soc in apu1 and add instantiation w/ leds-gpio, keys, etc, into the pcengines-apu2 driver.

Thanks for that work.  I have to admit someone from the fli4l linux
router distribution team also wrote LED and button drivers for the APU
boards, but never managed to upstream those. :-/

If someone is interested, those are spread in our Subversion
repository, but the apu drivers are here:

https://repo.nettworks.org/svn/fli4l/branches/4.0/trunk/src/packages/src/src/fli4l/hwsupp/pcengines-apu/

hmm, maybe I could pick up pieces for the FCH functionality that's
not supported yet (eg. wdt) ... not sure how much they differ between
different SoC versions.

Personally, I'd rather have mainline drivers for all that boards.
Don't know if it still makes sense for the older wrap or alix boards,
though.  I also have those lying around. ;-)

Well, somebody has to make his hands dirty, write those drivers, bring
them to mainline, and maintain them.
