display_clocks would be better there, we don't have to dissociate de1
with de2

How about de_clocks ? (See A80 DTSI)

and mixer0 here is enough too.

Is there several of them? Why not just use mixer if there's only one?

Nope, here it's tagged 0 only for consistency with other SoCs.

You have an extra new line here.
