What about arch/arm/include/asm/hardware/gic.h ?

Contrary to the current version of the bcm2835 IRQ controller driver
and the armada-370-xp IRQ controller driver, the GIC and VIC drivers
not only expose a <foo>_of_init() function, but also other functions
that are directly used by several non-DT capable ARM sub-architectures.

Of course, it works by leaving gic.h where it is now, but it sounds
strange to have the driver in drivers/irqchip/ and the header file in
arch/arm/include/asm/hardware/, especially if the goal is to be able to
use those drivers in arm64.

Best regards,

Thomas
