I spoke with Rob on IRC about the set and he preferred the private object be isolated in mdp5. So here's the atomic helper set rebased on Archit's series.
One notable difference is that I've dropped the first patch from that series which added a new private_obj lock to the core. Instead, it's located in mdp5_kms along with the global state (same as the state_lock which is currently there).
Thank you for your feedback thus far!

From: Archit Taneja architt@codeaurora.org
Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are implemented as a part of atomic state by subclassing drm_atomic_state.
The preferred approach is to use the drm_private_obj infrastructure available in the atomic core.
mdp5_global_state is introduced as a drm atomic private object. The two funcs mdp5_get_global_state() and mdp5_get_existing_global_state() are the two variants that will be used to access mdp5_global_state.
This will replace the existing mdp5_state struct (which subclasses drm_atomic_state) and the funcs around it. These will be removed later once we mdp5_global_state is put to use everywhere.
Changes in v3: - Added glob_state_lock instead of pushing it into the core - Added to the msm atomic helper patch set

From: Archit Taneja architt@codeaurora.org
This replaces the usage of the subclassed atomic state (mdp5_state) with a private_obj state embedded within drm_atomic_state. The latter method is the preferred approach, since it's simpler to implement and less prone to errors.
The new API replaces the older and equivalent mdp5_state usage in the following pattern: - References to "mdp5_kms->state" (i.e, the old/existing state) is replaced with mdp5_get_existing_global_state(). In the atomic_check path, this should be called with the glob_state_lock drm_modeset_lock alredy taken. - References to "mdp5_get_state()" are replaced with mdp5_get_global_state(). This acquires glob_state_lock and uses drm_atomic_get_private_obj_state() to create a new duplicated state.
Changes in v3: - Acquire glob_state_lock in mdp5_smp.c - Added to the msm atomic helper patch set

With the addition of "private_objs" in drm_atomic_state, we no longer need to subclass drm_atomic_state to store state of share resources that don't perfectly fit within planes/crtc/connector state information. We can now save this state within drm_atomic_state itself using the private objects.
Remove the infrastructure that allowed subclassing of drm_atomic_state in the driver.

Moving further towards switching fully to the the atomic helpers, this patch removes the hand-rolled worker nonblock commit code and uses the atomic helpers commit_work model.
Changes in v2: - Remove commit_destroy() - Shuffle order of commit_tail calls to further serialize commits - Use stall in swap_state to avoid abandoned events on disable Changes in v3: - Rebased on Archit's private_obj set
