Timer Interrupt.

Dear ALL,

	I am going to use the timer1 interrupt of etrax in my device driver,
	I can't find any good example of using interrupts in the source tree.
	Can i follow the  linux device driver prototype functions(like
	int request_irq(unsigned int irq,
	   void (*handler)(int, void *, struct pt_regs *),
   	   unsigned long flags, 
           const char *dev_name,
           void *dev_id);

	   void free_irq(unsigned int irq, void *dev_id);

	The IRQ of timer1 is 3? as i found that the timer0 is 2
	in /linux/arch/cris/kernel/time.c
