Agreed. In addition, if you look specifically at triggers, I've seen so
far:
- The new SA_* trigger stuff
- The IRQ_TYPE_* stuff
- The definitions of bits in struct resource of interrupts in ioport.h
- The old IRQ_LEVEL
- Various arch specific things that duplicate it again
In addition, it's different bits with different organisation (for
example, the IRQ_TYPE can express dual edge), etc...
In my new powerpc IRQ rework, I'm wiping out our own definitions for
triggers and using IRQ_TYPE_* accross the range. I'm howveer not using
the SA_* stuff at all at this point (that is, I'm neither converting the
trigger type of a given interrupt to SA_* and putting it in the
action/desc, nor honoring the SA_* triggers passed in request_irq at
this point). It might be nice to do so, but I find that there is just
way too much confusion at the moment.
Ben.
