[PATCH 15/28] arm64: dts: qcom: sc7180: Fix swapped USB QMP PHY vdda-phy/vdda-pll supplies
From: Manivannan Sadhasivam via B4 Relay
Date: Mon Aug 03 2026 - 02:46:31 EST
From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxxxxxxxx>
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.
