| |
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 -- Daniel
