Subject: [PATCH 3/5] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
Date: Wed, 8 May 2019 13:42:13 -0700 [thread overview]
Message-ID: <20190508204219.31687-4-robdclark@gmail.com> (raw)
In-Reply-To: <20190508204219.31687-1-robdclark@gmail.com>
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
