That's not right either, it would retrieve the wrong IRQ from the
interrupts property if you have holes -- try with something like
{ 0 64, 128, 64 }. The desired behavior there is:
offset = 0 irq_index = 0
offset = 1 irq_index = 1
offset = 4 irq_index = 2
offset = 5 irq_index = 3
I think the right code (untested) might be:
err = fsl_msi_setup_hwirq(msi, dev, offset + j, irq_index);
and
cascade_data->index = offset;
