Great! Sorry for not responding earlier.

I wonder if it would make sense to extend the interrupt api to provide
a bitmap of all supported sense configurations supported by the
driver... That way the driver would tell the interrupt controller
which configurations it supports and it's up to the interrupt
controller pick one of them. Then the driver reads back which
configuration that was selected by the interrupt controller and sets
up the hardware it controls accordingly.

Or maybe that is too complicated, I'm not sure. But the current
framework seems a bit too limited IMO, especially if the interrupt
controller only supports a certain sense configuration.

The best solution may be the other way around though, where the
interrupt controller provides a bitmap of supported sense
configurations that the driver may choose from...
