In this case, they should be in clocksource/arm_arch_timer.c and irqchip/irq-gic* only. The driver will expose necessary info to KVM via public interfaces. > 2.

GIC can follow the same approach (though trickier than arch_timer, due to GICv2 and GICv3). > > Any though? I am also in favour of this approach, it makes sense to decouple these parts from DT/ACPI.
