Subject: gpio + separate interrupts on rising / falling

Hi folks,

I've got device with some strange device that triggers two irqs via one
line. Rising means buffer A filled, falling mean buffer B filled.

I'd like to handle that via two separate interrupts. Is it possible to
register both an rising and an falling edge irq on the same line ?
