The main intent of this patchset is to allow use of suspend/resume drm driver callbacks in KMS drivers, as these callbacks seems to me the best place to implement suspend/resume functionality in drm driver. Implementing this functionality in master component driver PM ops is problematic as those callbacks can be called asynchronously regardless of state/existence of drm device, thus it would require additional synchronization mechanism. Callbacks re-enabling requires small changes in i915 and exynos driver. The patchset contains also fix of exynos resume callback.
