Subject: [PATCH v3 3/3] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845
Date:   Thu, 22 Nov 2018 14:36:53 +0530
Message-Id: <20181122090653.3523-4-skolluku@codeaurora.org>
In-Reply-To: <20181122090653.3523-1-skolluku@codeaurora.org>
References: <20181122090653.3523-1-skolluku@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)
