Only one patch left in this series. This patch depends on [1] and [2] which have been merged through by Rafael through the power tree.
Changes since v3:
- first trip point increased to 90 degrees based on Matthias' testing
- Added Acks
Changes since v2:
- Split up the series into auto-register series for cpufreq[1] and
miscellaneous patches[2][3]. [1] and [2] are needed for this patch to
work.
- Merged the two DT patches into one. We end up with 2 passive and 1
critical trip point.
- Remove unncessary cooling map for critical trip point, we're shutting down at
that trip, duh!

Since all cpus in the big and little clusters, respectively, are in the
same frequency domain, use all of them for mitigation in the
cooling-map. We end up with two cooling devices - one each for the big
and little clusters.
