Oh cool! Sorry I missed that one. Your series is much more
comprehensive, so this patch of mine can be dropped. Thanks for your
work!

Would you mind chiming in on the other patches here, given your
knowledge of the hardware?

By the way, you guys don't seem to carry those patches of yours in the
Collabora tree [1]? Nor the TSADC updates as far as I can tell.
