I talked to David Box (CC'ed him to this reply). We can add an integer value to ACPI and request it during phy's probe using ACPI's Device Specific Data (_DSD). That would end the need to have phy functional during probe (being compatible to BYT-CR and to module support) and would be more compatible to DT as well.
