Hi developers, i made a patch for an PXA270-evalboard with DM9000 ethernet contoller. The Interrupt can be high- or low- active dependant of the wiring of the MDC-(57)pin. Because of this hardware dependency you shoud be able to configure this behaviour in "struct resource dm9000_resources[]" Please comment an review my patch which is attached here Thanksalot Jürgen Schindele
