Message

Move pm_runtime on hrtimer and raw ns time to get finer granularity

Patch 1 moves runtime_pm autosuspend on hrtimer framework

Patch 2 moves time accounting on raw ns. This patch initially used
ktime instead of raw ns but it was easier to move i915 driver on raw ns
than on ktime

Patch 3 fixes drm/i915 driver that uses PM core fields

Changes since v1:
- updated commit message of patch 1
- Added patches 2 & 3 to move runtime_pm accounting on raw ns
  
Thara Gopinath (1):
  PM/runtime:Replace jiffies based accouting with ktime based accounting

Vincent Guittot (2):
  PM/pm_runtime: move autosuspend on hrtimer
  drm/i915: Move to new PM core fields
