This patch series brings stability to PSR on VLV, CHV, HSW and BDW.
It fixes issues Matthew Garrett without causing the blank and frozen
screens Ivan Mitev was facing.
It also move the VLV/CHV workaround of that big delay from re-enable
to the first enable after modeset that was the real issue.
With this besides the stability this series brings more PSR
residency to these platforms.
However the enable by default is still out of this series and will come
only after an intensive QA.
Thanks,
Rodrigo.
