So you can't do a shared c

I was wondering about that.
What exactly is a chained handler? How is it different from a regular handler?

Hi,
Looks like 8xxx GPIO driver cannot properly handle interrupts
when multiple GPIO controllers exist in the system.
On Freescale P1022 there are 3 GPIO controllers. All 3 use
the same interrupt line, internal interrupt 31. If all controllers
are defined in device tree set_irq_chained_handler(
