[PATCH v4 4/4] drm/msm/mdss: Handle the reg bus ICC path

2023-12-02 Thread Dmitry Baryshkov
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.
