Hi Steev!
There's a bunch of driver changes and some fixes needed for this to
work that I sent later. I also sent out DT bindings updates for it. I
decided to target relevant maintainers with smaller chunks because I
have had more luck getting patches upstream this way than when sending
big series with everything in them. Given that QCom patches take ages
to get picked up, I figured the driver changes will be in next by
then.
Your best approach would be to use the public integration branch from
my tree[1] or the one rebased on top of Johan's tree[2].
