This series fixes a small issue with the CPC driver when A CM3 is present, where a redundant lock was taken. There are then additions to the pm-cps driver to add support for R6 CPUs such as the I6400, and additionally the CM3 present in the I6400. Finally we enable the cpuidle-cps driver for MIPSr6 CPUs.
