Changes in this version: Included the 5 left over patches. Patches 1 and 5 have changed, so I have removed Maarten's R-B for patch 5.
1/5: Added NULL checks 5/5: Fixed vcpi slot accounting when atomic_release() is called multiple times within an atomic_check()
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 (5): 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: Connector helper function to release resources drm/dp: Track MST link bandwidth
