Note that the interrupt map is board specific, so this should probably go in the board.dts file rather than platform.dtsi. For this particular board, the interrupt lines appear to have been badly configured so all slots use the same interrupt 0 for IntA. IIRC This also means you can probably use <0 0 0 7> as the mask and just specify each of the four interrupts once. A properly wired board would swizzle the interrupts so that each slot has a different IRQ for its IntA line. Arnd
