I was hoping for your input here. Can you elaborate on UIO driver?
What interface to user space do you suggest. I have requirements that a user space should be able to subscribe
and unsubscibe for one or several of the 112 ab8500 events.
Debugfs was the choice because I already had register access there and it can easily be compiled away.
I also wanted a clear connection to the irq_chip solution in the ab8500-core driver.
