Subject: [v5 3/3] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
Date: Wed,  9 Jan 2019 23:22:05 +0530
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
