This series introduces a cpuidle driver for systems based around the MIPS Coherent Processing System, ie. those with a Coherence Manager and optionally a Cluster Power Controller. The resulting driver is very much foundational work to which deeper power states will later be added. Tested on Malta using interAptiv bitstreams with both 1 & 2 VPEs in each of 2 cores, and a multi-core proAptiv bitstream. This series depends upon the CM changes of my "MIPS CPS SMP" series.
