The pll fallout is fixes for the initial feature that was in the merge window,
Tuning plls for monitors is always a pain in the ass, the previous algorithm
took a couple of kernels a few years back to get where it was, unfortunately
HDMI came along and showed up a bunch of its shortcomings. I'm happy
Alex and Christian are on top of things in terms of tracking regressions
and making sure they get fixed,

the AUX fix yes I'm a bit pissed off about myself, but I missed a pull
from a few
weeks ago, felt guilty, and maybe should have chosen the other path and let it
wait a merge,

Christian just sent me a -fixes pull with all of these in it and I'll
send it on to you
in a few mins.

Dave.
