Subject: [PATCH 1/5] dt-bindings: display/msm: Add reg bus interconnect
Date: Mon, 17 Apr 2023 17:30:15 +0200 [thread overview]
Message-ID: <20230417-topic-dpu_regbus-v1-1-06fbdc1643c0@linaro.org> (raw)
In-Reply-To: <20230417-topic-dpu_regbus-v1-0-06fbdc1643c0@linaro.org>
Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's
another path that needs to be handled to ensure MDSS functions properly,
namely the "reg bus", a.k.a the CPU-MDSS interconnect.
Gating that path may have a variety of effects.. from none to otherwise
inexplicable DSI timeouts..
Describe it in bindings to allow for use in device trees.
