Subject: [PATCH v6 05/17] dt-bindings: display/msm: qcom,sm8750-mdss: Add SM8750
Date: Tue, 10 Jun 2025 16:05:43 +0200	[thread overview]
Message-ID: <20250610-b4-sm8750-display-v6-5-ee633e3ddbff@linaro.org> (raw)
In-Reply-To: <20250610-b4-sm8750-display-v6-0-ee633e3ddbff@linaro.org>

Add MDSS/MDP display subsystem for Qualcomm SM8750 SoC, next generation
with two revisions up of the IP block comparing to SM8650.

Reviewed-by: Rob Herring (Arm) <robh@kernel.org>
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Changes in v3:
1. Properly described interconnects
2. Use only one compatible and contains for the sub-blocks (Rob)
