FROMLIST: arm64: dts: qcom: lemans: add mdss1 display device nodes && FROMLIST: arm64: dts: qcom: lemans-ride: Enable mdss1 display Port by yashgupta2126 · Pull Request #291 · qualcomm-linux/kernel

yashgupta2126 · 2026-02-17T11:16:12Z

Add devicetree changes to enable second Mobile Display Subsystem (mdss1), Display Processing Unit(DPU), Display Port(DP) controllers and eDP PHYs on the Qualcomm Lemans platform.

This change enables DP controllers, DPTX0 and DPTX1 alongside their corresponding PHYs of mdss1 which corresponds to edp2 and edp3.

On multi-DPU configurations, the GPU binds to the first probed DPU by default. This binding prevents subsequent DPUs from probing successfully, effectively blocking multi-display support. This issue is observed on targets like SA8775P. Enable separate_gpu_kms by default. This allows the GPU and DPUs to be probed independently, ensuring that all DPU instances are initialized correctly.
