Hi Scott, I am able to register the IRQ now once I add the call irq_set_default_host in cpm2_pic.
This is a band-aid at best and will probably not be accepted upstream. You should -really- describe your interrupt in the device-tree instead. Ben.
But when I call enable_irq the code throws the below warning and gives exception in enable irq at spin_unlock_irqrestore(&desc->lock, flags); in enable_irq. printk(KERN_WARNING "Unbalanced enable for IRQ %d\n", irq); Regards, Smitha Please do not print this email unless it is absolutely necessary.
