[v2] Add interconnect nodes and paths for MSM8953 SoC

[PATCH v2 1/2] dt-bindings: msm: qcom,mdss: Document interconnect paths

Posted by Luca Weiss 9 months, 3 weeks ago

Document two interconnect paths found on the MDSS on MSM8953.

There's also some interconnect paths defined in the mdp5 schema, both
drivers accept it. Newer mdss schemas seem to prefer mdp0-mem + cpu-cfg
in the mdss schema instead of in the dpu subnode. Since there's no
cpu-cfg defined with mdp5, I've added these paths here.
