I use two CONFIG_OF in this file. The first one is used to record register base address of interrupt controller. In legacy code, the register address is hardcoding. Do you mean that I should remove this CONFIG_OF?Unless it's a noticeable performance impact, I would recommend just always using the mmp_icu_base variable, even for when CONFIG_OF is disabled. ? ? ? ?Arnd
But I appended new irq handler for DT support. I still need to reserve this CONFIG_OF since I need to keep compatible with legacy code. While everything in arch-mmp is moved into DT, I can remove this CONFIG_OF. For the second CONFIG_OF, I can try to remove it. Best Regards Haojian
