Subject: [PATCH mvebu-dt64] arm64: dts: turris-mox: fix usb3 phys
Date: Tue, 7 Jul 2026 23:08:29 +0200 [thread overview]
Message-ID: <20260707210830.3708-1-tomas.macholda@nic.cz> (raw)
After commit 00e6d608fe80b0f6 ("arm64: dts: marvell: armada-37xx: swap
PHYs' order in USB3 controller node") swapped USB3 PHY order, USB
initialization breaks on Turris MOX.
This regression was exposed by commit 91ddf6f722084383 ("phy: marvell:
mvebu-a3700-utmi: fix incorrect USB2_PHY_CTRL register access") which
made USB2 devices not work at all.
Fix the issue by explicitly adding all USB3 PHYs and PHY names to
Turris MOX device-tree.
Fixes: 7109d817db2e ("arm64: dts: marvell: add DTS for Turris Mox")
