So you are saying ACPI is just DT stuff into tables? Then why bother
with ACPI? Just use DT.

Right, O.K. Please document anything which phylink already supports:

hylink.c:		ret = fwnode_property_read_u32(fixed_node, "speed", &speed);
phylink.c:		if (fwnode_property_read_bool(fixed_node, "full-duplex"))
phylink.c:		if (fwnode_property_read_bool(fixed_node, "pause"))
phylink.c:		if (fwnode_property_read_bool(fixed_node, "asym-pause"))
phylink.c:		ret = fwnode_property_read_u32_array(fwnode, "fixed-link",
phylink.c:		ret = fwnode_property_read_u32_array(fwnode, "fixed-link",
phylink.c:	if (dn || fwnode_property_present(fwnode, "fixed-link"))
phylink.c:	if ((fwnode_property_read_string(fwnode, "managed", &managed) == 0 &&

If you are adding new properties, please do that In a separate patch,
which needs an ACPI maintainer to ACK it before it gets merged.
