Hi,

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. > > Cheers, > Samuel. >
