The unit-address of the node should be somehow related to 'reg'
property.  Can you please help me understand how they are related?

Please have a newline in between nodes.

The unit-address of the fsl-mc node is the base address of the MC portal described in the first region of the 'reg' property and formed using the 2 address cells.
Hope this helps.

Will do. 

Should I send a rework of this patch right away or better to wait for the merge window to close?

Ah, sorry, I forgot that the address-cells is 2.

Either way is fine, as I will rebase my branch to v4.15-rc1 after merge
window closes.

Just noticed this - the unit-address should be hex number, so it should
be dpmac@a rather than dpmac@10, I think.

Yes, that is right, it should be dpmac@a. Will change it.
