This patch landed recently in linux-next as commit cf4b94c8530d ("of:
property: fw_devlink: Add support for "phy-handle" property"). It breaks
ethernet operation on my Amlogic-based ARM64 boards: Odroid C4
(arm64/boot/dts/amlogic/meson-sm1-odroid-c4.dts) and N2
(meson-g12b-odroid-n2.dts) as well as Khadas VIM3/VIM3l
(meson-g12b-a311d-khadas-vim3.dts and meson-sm1-khadas-vim3l.dts).
In case of OdroidC4 I see the following entries in the
/sys/kernel/debug/devices_deferred:
ff64c000.mdio-multiplexer
ff3f0000.ethernet
Let me know if there is anything I can check to help debugging this issue.
