From f6a787a5e238599f3543c3dccf0abd6030dd48e3 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 3 Aug 2026 08:34:10 +0200 Subject: [PATCH] arm64: dts: qcom: qcm6490: Fix swapped USB QMP PHY vdda-phy/vdda-pll supplies The QMP PHY expects the vdda-phy supply to be around 0.88V and the vdda-pll supply to be 1.2V. But these two supplies are swapped for the USB QMP PHYs on these boards, feeding 1.2V to vdda-phy and 0.9V to vdda-pll. Fix it by swapping the two supplies back. Fixes: 9af6a9f32ad0 ("arm64: dts: qcom: Add base qcm6490 idp board dts") Fixes: a319cf4a4b09 ("arm64: dts: qcom: qcm6490: Introduce the Particle Tachyon") Fixes: eee9602ad649 ("arm64: dts: qcom: qcm6490: Add device-tree for Fairphone 5") Fixes: 249666e34c24 ("arm64: dts: qcom: add QCM6490 SHIFTphone 8") Reported-by: Konrad Dybcio Assisted-by: Claude:opus-4-8 Signed-off-by: Manivannan Sadhasivam Reviewed-by: Luca Weiss Link: https://lore.kernel.org/r/20260803-phy-supply-fix-v1-12-5880630cde3e@oss.qualcomm.com Signed-off-by: Bjorn Andersson --- arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts | 4 ++-- arch/arm64/boot/dts/qcom/qcm6490-idp.dts | 4 ++-- arch/arm64/boot/dts/qcom/qcm6490-particle-tachyon.dts | 4 ++-- arch/arm64/boot/dts/qcom/qcm6490-shift-otter.dts | 4 ++-- 4 files changed, 8 insertions(+), 8 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts b/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts index f072bd96c7d4..f41ad446a39e 100644 --- a/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts +++ b/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts @@ -1554,8 +1554,8 @@ }; &usb_1_qmpphy { - vdda-phy-supply = <&vreg_l6b>; - vdda-pll-supply = <&vreg_l1b>; + vdda-phy-supply = <&vreg_l1b>; + vdda-pll-supply = <&vreg_l6b>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/qcm6490-idp.dts b/arch/arm64/boot/dts/qcom/qcm6490-idp.dts index bdc02260f902..58cce89a0c1c 100644 --- a/arch/arm64/boot/dts/qcom/qcm6490-idp.dts +++ b/arch/arm64/boot/dts/qcom/qcm6490-idp.dts @@ -1141,8 +1141,8 @@ }; &usb_1_qmpphy { - vdda-phy-supply = <&vreg_l6b_1p2>; - vdda-pll-supply = <&vreg_l1b_0p912>; + vdda-phy-supply = <&vreg_l1b_0p912>; + vdda-pll-supply = <&vreg_l6b_1p2>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/qcm6490-particle-tachyon.dts b/arch/arm64/boot/dts/qcom/qcm6490-particle-tachyon.dts index 94eebb7de7b9..5bb33a8a9830 100644 --- a/arch/arm64/boot/dts/qcom/qcm6490-particle-tachyon.dts +++ b/arch/arm64/boot/dts/qcom/qcm6490-particle-tachyon.dts @@ -841,8 +841,8 @@ }; &usb_1_qmpphy { - vdda-phy-supply = <&vreg_l6b_1p2>; - vdda-pll-supply = <&vreg_l1b_0p912>; + vdda-phy-supply = <&vreg_l1b_0p912>; + vdda-pll-supply = <&vreg_l6b_1p2>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/qcm6490-shift-otter.dts b/arch/arm64/boot/dts/qcom/qcm6490-shift-otter.dts index e5366cfd3a02..cf74b3664cf5 100644 --- a/arch/arm64/boot/dts/qcom/qcm6490-shift-otter.dts +++ b/arch/arm64/boot/dts/qcom/qcm6490-shift-otter.dts @@ -975,8 +975,8 @@ }; &usb_1_qmpphy { - vdda-phy-supply = <&vreg_l6b>; - vdda-pll-supply = <&vreg_l1b>; + vdda-phy-supply = <&vreg_l1b>; + vdda-pll-supply = <&vreg_l6b>; status = "okay"; };
