I have pretty simple code that I did a long time ago
irqreturn_t irq_handler(int irq, void *dev_id, struct pt_regs *regs)
{
..
return IRQ_HANDLED;
}
request_irq(irq,
&irq_handler,
SA_INTERRUPT,
"irq handler",
NULL);
That code runs on MPC8272 and 2.6.18 kernel.
It triggers IRQ on low level (I thought it was falling edge by default).
So, as long as I have input low level I have hundreds of calls. Pretty
much it keeps calling IRQ handling routine.
How do I make it to trigger on falling edge?
Thank you,
Dmytro
