+Subject: [PATCH 657/660] arm64: dts: uDPU: fix comphy definitions
+
+The uDPU uses both ethernet controllers, which ties up COMPHY 0 for
+eth1 and COMPHY 1 for eth0, with no USB3 comphy. The addition of
+COMPHY support made the kernel override the setup by the boot loader
+breaking this platform. Delete the USB3 COMPHY definition at platform
+level, and add phy specifications for the ethernet channels.
+
+Fixes: bd3d25b07342 ("arm64: dts: marvell: armada-37xx: link USB hosts with their PHYs")
