From ff7155df9a9543af1eb9722563e6dcda33c1a97d Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 3 Aug 2026 08:34:00 +0200 Subject: [PATCH] arm64: dts: qcom: sc8280xp-blackrock: 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 this board, feeding 1.2V to vdda-phy and 0.9V to vdda-pll. Fix it by swapping the two supplies back.
