If anyone has any objections, please let me know. ------------------ From: Konrad Dybcio [ Upstream commit b3ee497970c63cea37976aeaa84bac39611fe0eb ] Neither of the two Gen4x4 PHYs found on Purwa supports bifurcation. The PHY is however physically laid out as if it were to, since there are two separate ports (A/B). Split out a new if-then block to un-require the bifurcation register handle to squash this warning: purwa-iot-evk.dtb: phy@1bd4000 (qcom,x1p42100-qmp-gen4x4-pcie-phy): 'qcom,4ln-config-sel' is a required property Fixes: 2e1ffd4c1805 ("dt-bindings: phy: qcom,qmp-pcie: Add X1P42100 PCIe Gen4x4 PHY") Reported-by: Rob Herring Closes: https://lore.kernel.org/linux-arm-msm/176857775469.1631885.16133311938753588148.robh@kernel.org/ Signed-off-by: Konrad Dybcio Acked-by: Rob Herring (Arm) Link: https://patch.msgid.link/20260610-topic-purwa_phy_shutup_warning-v2-1-951c1fbfe9b2@oss.qualcomm.com Signed-off-by: Vinod Koul Signed-off-by: Sasha Levin --- .../bindings/phy/qcom,sc8280xp-qmp-pcie-phy.yaml | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-pcie-phy.yaml b/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-pcie-phy.yaml index 119b4ff36dbd66..19d7de3ce7a967 100644 --- a/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-pcie-phy.yaml +++ b/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-pcie-phy.yaml @@ -134,13 +134,22 @@ allOf: items: - description: port a - description: port b - required: - - qcom,4ln-config-sel else: properties: reg: maxItems: 1 + - if: + properties: + compatible: + contains: + enum: + - qcom,sc8280xp-qmp-gen3x4-pcie-phy + - qcom,x1e80100-qmp-gen4x4-pcie-phy + then: + required: + - qcom,4ln-config-sel + - if: properties: compatible: -- 2.53.0
