Subject: [PATCH 01/11] dt-bindings: display/msm: split qcom, mdss bindings
Date: Sun, 26 Jun 2022 02:25:03 +0300 [thread overview]
Message-ID: <20220625232513.522599-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220625232513.522599-1-dmitry.baryshkov@linaro.org>
Split Mobile Display SubSystem (MDSS) root node bindings to the separate
yaml file. Changes to the existing (txt) schema:
- Add optional "vbif_nrt_phys" region used by msm8996
- Make "bus" and "vsync" clocks optional (they are not used by some
platforms)
- Add (optional) "core" clock added recently to the mdss driver
- Add optional resets property referencing MDSS reset
- Define child nodes together with compatibles

-- interrupts: The interrupt signal from MDSS.
-- interrupt-controller: identifies the node as an interrupt controller.
