Sigh.. Thanks Jai for stepping and trying to make this work, but I think
this series is a lot out of whack. Apparently somewhere in this series
is a patch for j721s2 that breaks proper boot. I spent quite a while
bisecting across boards to find it, So, I am just going to skip this
series for this release (and dependencies)

Next time for this series: I recommend submitter provide test
logs for every single platform touched.

I have'nt debugged, but typically that looks like some one decided to
pull the voltage low on a key rail.

Let me see if I can pick the interrupt range fix at least since
should'nt be dependent on this.
