From f35723d6b6a2f6d6fc3cf2fc3ff556436f76ebd4 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 3 Aug 2026 08:34:08 +0200 Subject: [PATCH] arm64: dts: qcom: sm8550: 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 0.88V to vdda-pll. Fix it by swapping the two supplies back. Fixes: b5e25ded2721 ("arm64: dts: qcom: sm8550: add support for the SM8550-HDK board") Fixes: 772e6bc4a0a9 ("arm64: dts: qcom: sm8550-mtp: Add USB PHYs and HC nodes") Fixes: d228efe88469 ("arm64: dts: qcom: sm8550-qrd: add QRD8550") Fixes: 39c596304e44 ("arm64: dts: qcom: Add SM8550 Xperia 1 V") 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-v1-10-5880630cde3e@oss.qualcomm.com Signed-off-by: Bjorn Andersson --- arch/arm64/boot/dts/qcom/sm8550-hdk.dts | 4 ++-- arch/arm64/boot/dts/qcom/sm8550-mtp.dts | 4 ++-- arch/arm64/boot/dts/qcom/sm8550-qrd.dts | 4 ++-- arch/arm64/boot/dts/qcom/sm8550-sony-xperia-yodo-pdx234.dts | 4 ++-- 4 files changed, 8 insertions(+), 8 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sm8550-hdk.dts b/arch/arm64/boot/dts/qcom/sm8550-hdk.dts index 58c71ac67da5..82fb10ed6b6b 100644 --- a/arch/arm64/boot/dts/qcom/sm8550-hdk.dts +++ b/arch/arm64/boot/dts/qcom/sm8550-hdk.dts @@ -1649,8 +1649,8 @@ }; &usb_dp_qmpphy { - vdda-phy-supply = <&vreg_l3e_1p2>; - vdda-pll-supply = <&vreg_l3f_0p88>; + vdda-phy-supply = <&vreg_l3f_0p88>; + vdda-pll-supply = <&vreg_l3e_1p2>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/sm8550-mtp.dts b/arch/arm64/boot/dts/qcom/sm8550-mtp.dts index 5769be83cfbd..7c634572c6b7 100644 --- a/arch/arm64/boot/dts/qcom/sm8550-mtp.dts +++ b/arch/arm64/boot/dts/qcom/sm8550-mtp.dts @@ -971,8 +971,8 @@ }; &usb_dp_qmpphy { - vdda-phy-supply = <&vreg_l3e_1p2>; - vdda-pll-supply = <&vreg_l3f_0p91>; + vdda-phy-supply = <&vreg_l3f_0p91>; + vdda-pll-supply = <&vreg_l3e_1p2>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/sm8550-qrd.dts b/arch/arm64/boot/dts/qcom/sm8550-qrd.dts index 144e105b734f..473ec4e27daf 100644 --- a/arch/arm64/boot/dts/qcom/sm8550-qrd.dts +++ b/arch/arm64/boot/dts/qcom/sm8550-qrd.dts @@ -1549,8 +1549,8 @@ }; &usb_dp_qmpphy { - vdda-phy-supply = <&vreg_l3e_1p2>; - vdda-pll-supply = <&vreg_l3f_0p88>; + vdda-phy-supply = <&vreg_l3f_0p88>; + vdda-pll-supply = <&vreg_l3e_1p2>; status = "okay"; }; diff --git a/arch/arm64/boot/dts/qcom/sm8550-sony-xperia-yodo-pdx234.dts b/arch/arm64/boot/dts/qcom/sm8550-sony-xperia-yodo-pdx234.dts index 0e6ed6fce614..367f6eae5e65 100644 --- a/arch/arm64/boot/dts/qcom/sm8550-sony-xperia-yodo-pdx234.dts +++ b/arch/arm64/boot/dts/qcom/sm8550-sony-xperia-yodo-pdx234.dts @@ -766,8 +766,8 @@ }; &usb_dp_qmpphy { - vdda-phy-supply = <&pm8550vs_2_l3>; - vdda-pll-supply = <&pm8550ve_l3>; + vdda-phy-supply = <&pm8550ve_l3>; + vdda-pll-supply = <&pm8550vs_2_l3>; status = "okay"; };
