Subject: [PATCH 1/5] dt-bindings: display: msm: qcm2290: Add Shikra MDSS
Date: Wed, 03 Jun 2026 20:29:26 +0530 [thread overview]
Message-ID: <20260603-shikra-display-v1-1-aeac1b94faa7@oss.qualcomm.com> (raw)
In-Reply-To: <20260603-shikra-display-v1-0-aeac1b94faa7@oss.qualcomm.com>
Shikra SoC uses the same MDSS/DPU/DSI hardware as QCM2290 (DPU 6.5),
sharing the same register layout, DSI controller and 14nm DSI PHY.
Add qcom,shikra-mdss to the qcm2290-mdss binding compatible enum
rather than introducing a separate binding file.
Register qcom,shikra-dsi-ctrl in dsi-controller-main.yaml alongside
qcom,qcm2290-dsi-ctrl, and update the qcm2290-mdss patternProperties
to accept both SoC-specific DPU and DSI controller compatibles.
