Subject: [PATCH v2 0/2] drm/panfrost: Tidy up the devfreq implementation

The devfreq implementation in panfrost is unnecessarily open coded. It
also tracks utilisation metrics per slot which isn't very useful. Let's
tidy it up!

Changes since v1:
 http://lkml.kernel.org/r/20190912112804.10104-1-steven.price%40arm.com
 * Rebased onto latest drm-misc-next, specifically after
   d18a96620411 ("drm/panfrost: Remove NULL checks for regulator")
 * Added tags

Steven Price (2):
  drm/panfrost: Use generic code for devfreq
  drm/panfrost: Simplify devfreq utilisation tracking
