Hi all,

   I have written an service routine for handling the GPIO_WAKEUP
interrupt PSC2_4 pin (MPC5200 Core), but I donno how to register this
routine into the kernel. 

I have connected an external circuit which generates interrupts to this
PSC2_4 pin, but I believe the Core doesnt know what to do when this
interrupt is generated without registering this routine ...

Help/Suggestions/Redirections please .......

--Cheers

request_irq/free_irq() are what you're looking for.
See include/linux/interrupt.h for the details.
