Subject: [PATCH v1 1/3] arm64: dts: qcom: sm8350: Add display system nodes
Date:   Tue, 17 Jan 2023 13:02:21 +0100
Message-Id: <20230117120223.1055225-2-rfoss@kernel.org>

From: Robert Foss <robert.foss@linaro.org>

Add mdss, mdss_mdp, dsi0, dsi0_phy nodes. With these
nodes the display subsystem is configured to support
one DSI output.
