From 8e1877c41c2ee4ad245e1c26c98f3b4cb2585162 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 3 Aug 2026 08:34:15 +0200 Subject: [PATCH] arm64: dts: qcom: sc8180x: 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.
