This looks good to me now. Thanks for making all the changes!

Reviewed-by: Stephan Gerhold <stephan@gerhold.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

Nitpick: &usb_hub_reset_pm has input-disable (and the two others below),
but this one doesn't.
