Ahh - oh weh - so simple! Thank you!

OK, my dts is now:
/ {
/* ... */
[EMAIL PROTECTED] {
/* ... */
[EMAIL PROTECTED] {
interrupt-parent = <500>;
interrupts = <1 2 2>;
};
/* ... */
};
/* ... */
};
And the corresponding code is:
struct intmod_priv {
/** Interrupt-Number */
int own_irq;
/** The of-device-node */
struct device_node *intmod_dev_node;
};
static int __init mod_init( void )
{
// ...
priv.intmod_dev_node = NULL;
priv.intmod_dev_node = of_find_node_by_name(NULL, "intpin");
priv.own_irq = irq_of_parse_and_map(priv.intmod_dev_node, 0);
request_irq(priv.own_irq, intmod_isr, IRQF_DISABLED , "intmod",
INTMOD_IRQ_BOARD);
// ...
Thank you and bye, my next question is following :-)
