Hi Marcin

What i want to avoid is adding something which partially works, and
then have to throw it all away and start again in order to add full
support.

If ACPI really limits interrupts to devices, maybe we need a totally
different representation of MDIO and PHYs in ACPI to what it used in
device tree? The same may be true for the Ethernet ports of the mvpp2?
They might have to be represented as real devices, not children of a
device? Maybe trying to map DT to ACPI on a one-to-one basis is the
wrong approach?
