I have been there before when submitting a first Apalis TK1 version:

https://lkml.org/lkml/2016/5/16/288

Upon Rob Herring's suggestion I changed it now all to dashes:

https://lkml.org/lkml/2016/5/27/399

Even in our downstream U-Boot:

http://git.toradex.com/cgit/u-boot-toradex.git/commit/?h=2015.04-torade
x-next&id=4ae2e657f3350422ad81b1632de156bdd9517206

Of course for Colibri iMX7 one could argue that we already sold a
couple hundred pieces still using underscores. However I guess we could
still change to dashes now as those were all prototype, sample and/or
beta.

Cheers
