We want these numbers to be in ns. So the default value would actually
be 2. The driver needs to convert the number in DT to a value to poke
into a PHY register. Please rename the property adi,rx-internal-delay-ns.

Same here.

Units? You should probably rename this adi,fifo-depth-bits and list
the valid values in bits.

It is not the PHY which decides this. The MAC indicates if it is EEE
capable to phylib. phylib looks into the PHY registers to determine if
the PHY supports EEE. phylib will then enable EEE
advertisement. Please remove this, and ensure EEE is disabled by
default.
