Subject: [v6 3/3] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
Date:   Wed, 23 Jan 2019 09:01:37 +0530
Message-Id: <1548214297-17697-4-git-send-email-jshekhar@codeaurora.org>
In-Reply-To: <1548214297-17697-1-git-send-email-jshekhar@codeaurora.org>
References: <1548214297-17697-1-git-send-email-jshekhar@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

Changes in v6:
	-None
