[PATCH v2 0/2] arm64: dts: qcom: sm8[56]50: correct MDSS interconnects

[Dmitry Baryshkov]

Both SM8550 and SM8650 misuse mdp1-mem interconnect path for the
LLCC->EBI path, while it should only be used for the MDP->EBI paths.

This kind of misuse can result in bandwidth underflows, possibly
degrading picture quality as the required memory bandwidth is divided
between all mdpN-mem paths (and LLCC-EBI should not be a part of such
division).

Drop mdp1-mem paths and use MDP-EBI path directly.
