    drm/i915: Agressive downclocking on Baytrail · 8fb55197
    Chris Wilson authored
    Reuse the same reclocking strategy for Baytail as on its bigger brethren,
    Sandybridge and Ivybridge. In particular, this makes the device quicker
    to reclock (both up and down) though the tendency now is to downclock
    more aggressively to compensate for the RPS boosts.
    
    v2: Rebase
    v3: Exclude Cherrytrail as Deepak was concerned that the increased
    number of register writes would wake the common powerwell too often.
