interrupt handling in AM1808

Other Parts Discussed in Thread: AM1808

Hi

       I am using AM1808 Experimenters kit. my kernekl version is 2.6.37. I would like to use GPIO interrupt in the board. we have add on card for j28 from the base board. I am using the GP4[14],GP4[15] pins for rising the interrupt. I am using  the fallowing functions functions in loadable module.

static int interrupt_handler(int irq,void *dev_id,struct pt_regs *regs) ------------------>  interrupt handler
static void interrupt_enable(void)                                                 ------------------->  necessary gpio configurations to capture the interrupt
request_irq(49,interrupt_handler,SA_INTERRUPT, "interrupt", NULL)---------------->  for registering the interrupt in Linux.

In "interrupt_enable" function what all configurations we need to do for capturing the interrupt.

can you please suggest the changes to be done in board config file and da850.c if any

Thanks
