Z8530_INTERRUPT(9)					     Public Functions Provided						Z8530_INTERRUPT(9)

NAME
       z8530_interrupt - Handle an interrupt from a Z8530

SYNOPSIS
       irqreturn_t z8530_interrupt(int irq, void * dev_id);

ARGUMENTS
       irq
	   Interrupt number

       dev_id
	   The Z8530 device that is interrupting.

DESCRIPTION
       A Z85[2]30 device has stuck its hand in the air for attention. We scan both the channels on the chip for events and then call the channel
       specific call backs for each channel that has events. We have to use callback functions because the two channels can be in different modes.

       Locking is done for the handlers. Note that locking is done at the chip level (the 5uS delay issue is per chip not per channel). c->lock
       for both channels points to dev->lock
