The FSL MPIC binding should be updated to point out how this works. Technically it's not a change to the binding itself, since it's defined in terms of register offset, but the explanatory text says "So interrupt 0 is at offset 0x0, interrupt 1 is at offset 0x20, and so on." which is not accurate for these new high interrupt numbers. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
