New power management work for Linux 5.1 includes the new "TEO" CPU idle governor for tickless systems, updates to the ARM Energy Aware Scheduling (EAS) added to Linux 5.0, optimizations to the auto-suspend code within the power management run-time framework, there is a new CPUFreq driver for Armada 8K devices, Intel P-State clean-ups, and various optimizations and code improvements.

Intel Jacobsville CPUs now are now supported by the Intel Idle driver as well as their Icelake and Jabosville hardware being added to the RAPL power-capping driver.
