From 2c45c4df3079acba14920b14286cebfea24ec603 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 3 Aug 2026 08:34:13 +0200 Subject: [PATCH] arm64: dts: qcom: sc7180: 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: 0b766e7fe5a2 ("arm64: dts: qcom: sc7180: Add USB related nodes") Fixes: 7ec3e67307f8 ("arm64: dts: qcom: sc7180-trogdor: add initial trogdor and lazor dt") Fixes: 4a9f8f8f2ada ("arm64: dts: qcom: Add Acer Aspire 1") Fixes: de8eed359759 ("arm64: dts: qcom: Add support for ECS LIVA QC710") Reported-by: Konrad Dybcio Assisted-by: Claude:opus-4-8 Signed-off-by: Manivannan Sadhasivam Link: https://lore.kernel.org/r/20260803-phy-supply-fix-v1-15-5880630cde3e@oss.qualcomm.com Signed-off-by: Bjorn Andersson --- arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts | 4 ++-- arch/arm64/boot/dts/qcom/sc7180-ecs-liva-qc710.dts | 4 ++-- arch/arm64/boot/dts/qcom/sc7180-idp.dts | 4 ++-- arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi | 4 ++-- 4 files changed, 8 insertions(+), 8 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts b/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts index 1514da636269..d9c70897b6f1 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-acer-aspire1.dts @@ -631,8 +631,8 @@ }; &usb_1_qmpphy { - vdda-phy-supply = <&vreg_l3c_1p2>; - vdda-pll-supply = <&vreg_l4a_0p8>; + vdda-phy-supply = <&vreg_l4a_0p8>; + vdda-pll-supply = <&vreg_l3c_1p2>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/sc7180-ecs-liva-qc710.dts b/arch/arm64/boot/dts/qcom/sc7180-ecs-liva-qc710.dts index b84da371581b..3100fab18787 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-ecs-liva-qc710.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-ecs-liva-qc710.dts @@ -563,8 +563,8 @@ }; &usb_1_qmpphy { - vdda-phy-supply = <&vreg_l3c_1p2>; - vdda-pll-supply = <&vreg_l4a_0p8>; + vdda-phy-supply = <&vreg_l4a_0p8>; + vdda-pll-supply = <&vreg_l3c_1p2>; /delete-property/ mode-switch; /delete-property/ orientation-switch; diff --git a/arch/arm64/boot/dts/qcom/sc7180-idp.dts b/arch/arm64/boot/dts/qcom/sc7180-idp.dts index 0bce3eefca2e..acfb9937651d 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-idp.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-idp.dts @@ -461,8 +461,8 @@ &usb_1_qmpphy { status = "okay"; - vdda-phy-supply = <&vreg_l3c_1p2>; - vdda-pll-supply = <&vreg_l4a_0p8>; + vdda-phy-supply = <&vreg_l4a_0p8>; + vdda-pll-supply = <&vreg_l3c_1p2>; }; &venus { diff --git a/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi b/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi index cd4a0e281cf8..0e0bc8543f71 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi @@ -998,8 +998,8 @@ ap_spi_fp: &spi10 { &usb_1_qmpphy { status = "okay"; - vdda-phy-supply = <&vdda_usb_ss_dp_1p2>; - vdda-pll-supply = <&vdda_usb_ss_dp_core>; + vdda-phy-supply = <&vdda_usb_ss_dp_core>; + vdda-pll-supply = <&vdda_usb_ss_dp_1p2>; }; &venus {
