    drm/msm/mdp5: Add global state as a private atomic object · 8d58ef34
    Archit Taneja authored
    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
    Changes in v4:
    - None
