[Intel-gfx] [PATCH 0/8] SKL S3, take 2

[Damien Lespiau]

Here's an update of my SKL S3 series:

  - Spotted a problem in the BXT resume path, we were missing a bxt_cdclk_init
    in the S3 path (we only had it in the runtime resume path). Consolidated
    the two paths to reduce the chances of this happening again.
  - Updated the SKL display re-init on resume based on Ville's comments. The
    major change is that we now poll the PCU for its ACK before changing CDCLK
    and this does solve the problem I was seeing (it typically takes 3/4 cycles
    separated by 10us to get the PCU to answer 'GO!')
