It looks like in your kernel version are some missing patches. Can you please
rebase your patches on top of this branch:
https://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git/log/?h=for-next
and please rename IMX6UL_CLK_ENET_REF to IMX6UL_CLK_ENET1_REF_SEL in
your dtsi.
Regards,
Oleksij
