Subject: [PATCH 02/28] arm64: dts: qcom: sc8280xp-blackrock: Fix swapped USB QMP PHY vdda-phy/vdda-pll supplies
Date: Mon, 03 Aug 2026 08:34:00 +0200	[thread overview]
Message-ID: <20260803-phy-supply-fix-v1-2-5880630cde3e@oss.qualcomm.com> (raw)
In-Reply-To: <20260803-phy-supply-fix-v1-0-5880630cde3e@oss.qualcomm.com>

From: Manivannan Sadhasivam <manivannan.sadhasivam@oss.qualcomm.com>

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.

Fixes: 16a7fed11714 ("arm64: dts: qcom: sc8280xp-blackrock: dt definition for WDK2023")
