Hi Rafael,

This pull request has a single patch which is a fix for the 
cpuidle-big.little driver. If the mcpm backend is not available because 
the CCI is not defined in the DT, the cpuidle driver will 
unconditionally assume it is and call the mcpm functions leading to a 
kernel WARNING.

Sudeep Holla fixed that by checking at the init time the mcpm is 
available before initializing the deeper idle states.

Thanks
