This commit fixes DT issue, so "fixes" tag should be:
Fixes: 44a94c7ef989 ("arm64: dts: allwinner: H5: Restore EMAC changes")

Here, a node with wrong phy-mode property was added to NanoPi Neo 2 board DT.  

Other than that, this patch is fine and once fixes tag is fixed, you can add:
Reviewed-by: Jernej Skrabec <jernej.skrabec@...il.com>

For next version, you should:
- change fixed tag
- add my review-by tag right above your signed-off-by tag
- mark patch as v2 (add "-v2" parameter to git format-patch)
- describe change right under "---" line

Note, if you borked something when sending, you should mark patch or patch 
series as "RESEND", so recipients don't look for changes in two subsequent e-
mails (--subject-prefix="RESEND PATCH").

Thanks for the fix!

Best regards,
Jernej
