Sorry for breaking ... but I have no bbw hw for testing ...
(This is maybe a reason for having something like an automated
  testsystem, see an example/proposal here:

https://github.com/hsdenx/tbot

see a demo for automated tests (running on a raspberry pi at my home
in hungary, boards are in munich/germany)
http://xeidos.ddns.net/buildbot/tgrid
)

But I removed this file as Mark Brown suggested it, see:

https://lkml.org/lkml/2015/10/21/581

So please introduce a "tps65217-am335x.dtsi" file ... Mark?

bye,
Heiko
