[Intel-gfx] [PATCH v7 0/4] Adding driver-private objects to atomic state

[Dhinakaran Pandiyan]

Changes in this version:
Used connector->atomic_check() to release vcpi slots instead of the
atomic_release() callback.

This series introduces void * type driver-private objects in core and adds
helper functions that operate on these private objects. Drivers need to
implement object-specific functions to swap and clear object states. The
advantage of having void * for these objects in the core is objects of different
types can be managed in the same atomic state array. The series implements
DP-MST link bw tracking using the driver-private object infrastructure.

Pandiyan, Dhinakaran (4):
  drm: Add driver-private objects to atomic state
  drm/dp: Introduce MST topology state to track available link bandwidth
  drm/dp: Add DP MST helpers to atomically find and release vcpi slots
  drm/dp: Track MST link bandwidth
