This should be list (items) with one const item.

Ditto

Let me quote:

"Phandle to syscon device requires a vendor, descriptive name and a
description"

You only got description right.

Drop, it is not defined here and already required by snps,dwmac.

You should not need it. Isn't snps,dwmac-3.50a already there? Anyway,
not alphabetically ordered...
