[Intel-gfx] [PATCH 0/5] Panel power sequencing improvements

[Paulo Zanoni]

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

Hi

This series was already posted to the mailing list as part of the Runtime PM
series. Since the runtime PM code touches some eDP code, I originally made this
series on top of runtime PM because I was hoping runtime PM would be merged
earlier, so I wouldn't need to rebase this series.

It seems that these patches actually fix real bugs, so Jesse asked me to send
this series on top of -nightly so we could try to merge it earlier. Here it is.

Besides rebasing, the differences are on patch 4 and 5: they now should address
the review comments from Chris, Ben and Jani.

Looks like this series fixes freedesktop.org bug 69693, and it also helps us
getting closer to fix 72211.

Thanks,
Paulo

  drm/i915: fix VDD override off wait
  drm/i915: save some time when waiting the eDP timings
  drm/i915: init the DP panel power seq variables earlier
