[Intel-gfx] [PATCH 0/4] SNB runtime PM fixes

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

When I originally wrote and tested SNB runtime PM it was working without any
errors, then I sent the patches to the mailing list and we ended up discarding
one of the patches that was needed. We ended up replacing that patch with a few
patches that only plugged the HSW holes, leaving SNB runtime PM broken since
then. Since I never got any bug report about this, I assumed SNB runtime PM was
working and didn't test things again... Then a long time later we got the bug
reports, and now we have fixes :)

Also notice that patch 1 was also sent as part of the "Runtime PM on DPMS on
HSW" series, so it's duplicated.

Thanks,
Paulo
