Error compiling kernel

Hy,
I tried to cross compiling the kernel bu i have this error :slight_smile:

drivers/net/phy/mdio_bus.c:42:26: fatal error: mdio_debugfs.h: Aucun fichier ou dossier de ce type
#include "mdio_debugfs.h"

I have tried to deleted #include "mdio_debugfs.h" in the files drivers/net/phy/mdio_bus.c but another errors come.

I tried to compile the mox-kernel-sfp-2020-08-work.

I have compiled the branch 5.4 and it was a success.
but the Mox D doesn’t work with.
