Alternatively, I could change the patch to use hardcoded values for now
(i.e replace ICU_GRP_NSR everywhere by 0x0), and then change it during
the next kernel cycle to use the #define value. I would really prefer
such a solution to a solution where merging the entire ICU DT change
would be delayed by one cycle.
Let me know what you prefer. Maybe Marc can say if the irqchip
maintainers can provide a stable branch containing the mvebu-icu.h file.
