This looks good to me now. Thanks for making all the changes!
Reviewed-by: Stephan Gerhold <stephan@...hold.net>
Please drop the tag again in case you send another version with any
larger changes. I'm happy to look at the patch again then. Not sure if
Caleb's R-b is still valid now after all the changes you made.
I found one more nitpick below, but it also exists in apq8016-sbc.dts.
Feel free to leave it as-is, I can fix it up for both sometime later.
Thanks,
Stephan
