Add ethernet phy node in at91rm9200ek.dts. The reg register is not specified, as it may differ depending on the init process of the board: ADDR0/1 phy pins are connected to PA13/14 rm9200 pins. Which means the phy will take its address from these pins during the reset process. The macb driver will launch a full scan on the mdio bus to discover the phy address.

rm9200 pio controller does not support specific edge detection. The line above should be replaced with: interrupts = <4 IRQ_TYPE_EDGE_BOTH>; or interrupts = <4 0>; Nicolas, I know you were planning to push this patch for 3.14. If you haven't done it yet (or if you changed your mind), I can send a new version including this fix.
