Subject: [v5 3/3] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
Date: Wed, 9 Jan 2019 23:22:05 +0530 [thread overview]
Message-ID: <1547056325-1919-4-git-send-email-jshekhar@codeaurora.org> (raw)
In-Reply-To: <1547056325-1919-1-git-send-email-jshekhar@codeaurora.org>
From: Sravanthi Kollukuduru <skolluku@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:
- None
