On some MSM chipsets, the display port controller is capable of supporting up to 4 streams.
To drive these additional streams, the pixel clocks for the corresponding stream needs to be enabled. Fixup the documentation of some of the bindings to clarify exactly which stream they correspond to, then add the new bindings and device tree changes. --- Changes in v3: - Fixed dtschema errors (Rob Herring) - Documented all pixel stream clocks (Dmitry) - Ordered compatibility list alphabetically (Dmitry) - Dropped assigned-clocks too (Dmitry) - Link to v2: https://lore.kernel.org/r/20250530-dp_mst_bindings-v2-0-f925464d3...@oss.qualcomm.com Changes in v2: - Rebased on top of next-20250523 - Dropped merged maintainer patch - Added a patch to make the corresponding dts change to add pixel 1 stream - Squashed pixel 0 and pixel 1 stream binding patches (Krzysztof) - Drop assigned-clock-parents bindings for dp-controller (Krzysztof) - Updated dp-controller.yaml to include all chipsets that support stream 1 pixel clock (Krzysztof) - Added missing minItems and if statement (Krzysztof) - Link to v1: https://lore.kernel.org/r/20241202-dp_mst_bindings-v1-0-9a9a43b06...@quicinc.com --- Abhinav Kumar (4): dt-bindings: Fixup x1e80100 to add DP MST support dt-bindings: clock: Add SC7280 DISPCC DP pixel 1 clock binding dt-bindings: display/msm: drop assigned-clock-parents for dp controller dt-bindings: display/msm: add stream pixel clock bindings for MST Jessica Zhang (1): arm64: dts: qcom: Add MST pixel streams for displayport .../bindings/display/msm/dp-controller.yaml | 53 +++++++++++----- .../bindings/display/msm/qcom,sa8775p-mdss.yaml | 14 +++-- .../bindings/display/msm/qcom,sar2130p-mdss.yaml | 11 ++-- .../bindings/display/msm/qcom,sc7180-mdss.yaml | 3 - .../bindings/display/msm/qcom,sc7280-mdss.yaml | 12 ++-- .../bindings/display/msm/qcom,sm7150-mdss.yaml | 5 -- .../bindings/display/msm/qcom,sm8750-mdss.yaml | 11 ++-- .../bindings/display/msm/qcom,x1e80100-mdss.yaml | 21 +++---- arch/arm64/boot/dts/qcom/sa8775p.dtsi | 34 +++++++--- arch/arm64/boot/dts/qcom/sar2130p.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sc7280.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sc8180x.dtsi | 20 ++++-- arch/arm64/boot/dts/qcom/sc8280xp.dtsi | 72 +++++++++++++++------- arch/arm64/boot/dts/qcom/sm8150.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sm8250.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sm8350.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sm8450.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sm8550.dtsi | 10 ++- arch/arm64/boot/dts/qcom/sm8650.dtsi | 10 ++- arch/arm64/boot/dts/qcom/x1e80100.dtsi | 30 ++++++--- include/dt-bindings/clock/qcom,dispcc-sc7280.h | 2 + 21 files changed, 235 insertions(+), 133 deletions(-) --- base-commit: 7a88d609b069b7d2f4d10113b18fea02921bedb1 change-id: 20241202-dp_mst_bindings-7536ffc9ae2f Best regards, -- Jessica Zhang <jessica.zh...@oss.qualcomm.com>
