See Documentation/devicetree/bindings/powerpc/fsl/mpic.txt For external interrupts, the first cell is equal to the IRQ number. For an example of specifying an external IRQ, see the RTC and PHY nodes in various mpc85xx device trees (e.g. mpc8536ds.dtsi). > What do I use with request_irq(?,....)? You need a virtual IRQ number. Typically this comes from irq_of_parse_and_map(). -Scott _______________________________________________ Linuxppc-dev mailing list [email protected] https://lists.ozlabs.org/listinfo/linuxppc-dev
