                    does not work

  Target Milestone: ---

Hello everyone! What is going on with autoloading modules for platform devices
from device tree? I've build image for raspberry pi, added device tree overlay
for enc28j60. I've checked: device tree node with this device exists in
/proc/device-tree/soc/spi at 7e204000. But lsmod does not shows that enc28j60.ko
is not loaded. In contrast of, raspbian distro successfully managed with this -
module loaded successfully.
Also, I've read this thread:
http://lists.busybox.net/pipermail/buildroot/2016-December/178779.html. As I
understand, command

find /sys/ -name modalias -print0 | xargs -0 sort -u -z | xargs -0
modprobe -abq

does not work.

Regards,

Artem Synytsyn
