Subject[PATCH 3/5] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
Date
From: Jayant Shekhar <jshekhar@codeaurora.org>

Add interconnect properties such as interconnect provider specifier
, the edge source and destination ports which are required by the
interconnect API to configure interconnect path for MDSS.

Changes in v2:
- None

Changes in v3:
- Remove common property definitions (Rob Herring)

Changes in v4:
- Use port macros and change port string names (Georgi Djakov)

Changes in v5-v7:
- None
