    drm/msm/mdp5: add support for MDP5 v1.3 · 3d47fd47
    Stephane Viau authored
    MDP5 has several functional blocks (ie: VIG/RGB pipes, LMs, ...).
    From one revision to another, these blocks' base addresses might
    change due to the number of instances present in the MDP5 hw.
    A way of dealing with these offset changes is to introduce
    dynamic offsets 'per block'.
    
    This change adds support for the new revision of MDP5: v1.3.
    The idea is to define one hw config per MDP version and select
    either one of them at runtime, after reading the MDP5 version.
    
    Once the MDP version is known, 'per block' dynamic offsets
    are initialized through a global pointer, which is then used for
    read/write register access.
