Per agreement with Konrad, picked up this patch series. Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's another path that needs to be handled to ensure MDSS functions properly, namely the "reg bus", a.k.a the CPU-MDSS interconnect. Gating that path may have a variety of effects. from none to otherwise inexplicable DSI timeouts. This series tries to address the lack of that. Changes since v1: - Dropped the DPU part, the MDSS vote seems to be enough - Reworked MDSS voting patch. Replaced static bw value with the per-platform confgurable values. - Added sm8450 DT patch.
