You can put it in <linux/irqchip/at91-aic.h>, there are already a few
headers there. But I think it's not the right solution.
*However*, ideally, this header should disappear completely. All the
register defines should go directly into the driver C file. The only
usage of the AIC defines outside of the IRQ driver are for debug prints
in the pm.c code, which I think you could get rid of.
Ditto for the at91_aic_{read,write} macros.
The NR_AIC5_IRQS can also move to the driver itself.
The only remaining one would be NR_AIC_IRQS, you can't get rid of it,
because it's used for the IRQ priority arrays. But I believe keeping
this one in <linux/irqchip/at91-aic.h> is reasonable.
Best regards,
Thomas
