On top of the last kernel tree I added a couple of DT changes for db820c
from the qcom landing tree necessary for bringing up the GPU, and a fix to
my OOB cleanups fro cheza. I also enabled the CPU clock driver for db820c
so we can turn on SMP and not leave jobs stranded on a 19Mhz CPU or whatever.
This causes us to need a bit of updating of our TF expectations since the
order of jobs changes a bit.
