[Freedreno] [PATCH v4 0/4] MDSS reg bus interconnect

[Dmitry Baryshkov]

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.

Dependencies: [1].
