[PATCH 3/5] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
From: Rob Clark
Date: Wed May 08 2019 - 16:44:28 EST
From: Jayant Shekhar <jshekhar@xxxxxxxxxxxxxx>
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:
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:
