What is this divider and why does the machine driver need to manually configure it?

I'm wondering if the FIQ code can be shared with the i.MX FIQ code? Not something that should block merging but it seems like it might be helpful for other platforms that need to use FIQ support.

Omit empty functions.

Eh? Waht's this about?

Why is this using devm_?
