I see. I just copied the interrupts that were listed in Allwinner sources. I'll drop the extra 2.
Also, do you know if the arch timers are usable on the A23?
I tried them (copying the "timer" section from A20 dtsi), but the system just hangs. I think I'll leave this for a follow up series.

My bad.
