Hmm. I think you're using a new revision of AV96. I added the board support
with an old version of it (might be an evaluation one). I don't have the delta
or changeset so can't compare. Anyway, DH started selling new boards and I
think the old ones were discontinued or not made available for purchase so we
don't have to worry about breaking the old one.

Fine. Just wanted to verify the PMIC part. But I got the information from
DH guy offline.

Right. Didn't know that it doesn't boot on newer boards. I do have one but
haven't tried mainline kernel on it, just vendor image for some demos. But
feel free to keep it as it is.

Thanks,
