Atm we toggle HW resources handled automatically by the DMC firmware. This is redundant and also interferes with the firmware's functionality. This patchset fixes this and also an old existing issue leaving RPM disabled all the time (see Damien's patch).
The patchset depends on Mika's firmware version blacklisting/capture [1] and Animesh' firmware loading redesign [2] patchset. Both of these are reviewed now. This patchset also relates to Patrik's DC5/DC6 rework patchset [3], but it's not dependent on it. After discussing with him on IRC I'd suggest the following merge order: Patchset [1], patchset [2], Patrik's firmware programming fix from his patchset [4], this patchset, the rest of Patrik's patchset [3]. Feel free to suggest a different order. I tested this on top of [1], [2], [4] on SKL-Y with eDP and DP outputs, DC5/6, PC9/10 residencies and S3/S4 suspend/resume seemed to work as expected. The basic D3 igt tests are also passing, as claimed by Damien's patch.
