It's okay, but I think you can simplify the interrupt handling a bit
more by not bothering to check for interrupts from unknown sources. If
a source hasn't been enabled, it shouldn't generate interrupts, right?
Besides, since the does nothing to stop further interrupts from unknown
sources, it would just keep getting further interrupts repeatedly in
that case.
Then you can get rid of the ui_DO, ui_DI, ui_Timer, and counters[]
variables and just check the registers directly (e.g. replace 'if
(ui_Timer == 1)' with 'if (inl(devpriv->amcc_iobase +
APCI1564_TIMER_IRQ_REG) & 0x01)').
