+Subject: [PATCH mvebu-dt64] arm64: dts: turris-mox: fix usb3 phys
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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")
