Patch 1 adds mode-switch to the QMP Combo PHY node in kodiak.dtsi, which is required for the PHY to respond to USB-C Alternate Mode negotiation and switch into 4-lane DP configuration. Patch 2 moves the data-lanes property from individual board files into kodiak.dtsi since the PHY-to-controller wiring is fixed in silicon. It also removes redundant remote-endpoint and orientation-switch overrides from qcs6490-rb3gen2 and qcs6490-thundercomm-rubikpi3 that are already covered by the SoC dtsi. Patch 3 updates data-lanes from <0 1> to <0 1 2 3> in kodiak.dtsi now that mode-switch is in place, enabling the full 4-lane DP link. Signed-off-by: Mahadevan P --- Changes in v2: - Split single patch into 3 patches. - Move mode-switch and data-lanes to kodiak.dtsi instead of board file (Neil Armstrong, Konrad Dybcio) - Remove redundant board-level endpoint and orientation-switch overrides now covered by kodiak.dtsi - v1 received a Reviewed-by from Dmitry on the combined change; that tag has been dropped pending re-review of the split. --- Mahadevan P (3): arm64: dts: qcom: kodiak: allow mode-switch events to reach the QMP Combo PHY arm64: dts: qcom: kodiak: move dp data-lanes to SoC dtsi arm64: dts: qcom: kodiak: Set up 4-lane DP arch/arm64/boot/dts/qcom/kodiak.dtsi | 2 ++ arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts | 4 ---- arch/arm64/boot/dts/qcom/qcm6490-particle-tachyon.dts | 4 ---- arch/arm64/boot/dts/qcom/qcs6490-rb3gen2.dts | 11 ----------- arch/arm64/boot/dts/qcom/qcs6490-thundercomm-minipc-g1iot.dts | 1 - arch/arm64/boot/dts/qcom/qcs6490-thundercomm-rubikpi3.dts | 3 --- arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi | 1 - 7 files changed, 2 insertions(+), 24 deletions(-) --- base-commit: 452c3b1ea875276105ac90ba474f72b4cd9b77a2 change-id: 20260420-kodiak_v2-d7a06d50db5e Best regards, -- Mahadevan P
