    ARM: nomadik: bump the IRQ numbers again · d9621176
    Linus Walleij authored
    Bump the IRQ numbers from offset at 1 (right above NO_IRQ)
    to 32. This is the painful way to learn that if you're using
    SPARSE_IRQ and avoid to define .nr_irqs in your machine,
    the first 16 IRQs will be pre-allocated, and the IRQdomain
    code (as the VIC core code before it) will then assume
    that all IRQ descriptors are pre-allocated, and 16 of them
    are - by somebody else. So mapping the IRQs will fail in
    irq_create_mapping(). Moving the offset upward rids us of
    this problem.
