[PATCH 3/3] dt-bindings: msm/disp: Introduce interconnect bindings for MDSS on SDM845

From: Sravanthi Kollukuduru <hidden>
Date: 2018-10-08 09:27:30
Also in: dri-devel, linux-arm-msm
Subsystem: drm driver for qualcomm display hardware, drm drivers, drm drivers and misc gpu patches, open firmware and flattened device tree bindings, the rest · Maintainers: Rob Clark, Dmitry Baryshkov, David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

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.
