[Freedreno] [PATCH v3 0/6] 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.

Changes since v2:
- Rebased on top of msm/next aka 6.6-rc2, Dropped merged patches.
- Dropped the *1000 factor from reg-bus BW values (Konrad).

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.
