Hello,
This patch series move the at91 AIC (Advance Interrupt Controller)
driver to the irqchip subsystem directory (drivers/irqchip).
It also make use of IRQCHIP_DECLARE to register irqchip for dt boards
instead of using the machine specific "init_irq" function.
Finally it register the arch specific irq handler inside the the init
functions using set_handle_irq. This way we can remove all the machine
specific "handle_irq".
This patch series was tested on kizbox board (sam9g20 SoC) using
device tree. Could someone test it on other boards (both dt and non dt)?
Best Regards,
Boris

Move arch/arm/mach-at91/irq.c to drivers/irqchip/irq-at91.c.
Move arch/arm/mach-at91/at91_aic.h to
arch/arm/mach-at91/include/mach/at91_aic.h to avoid ugly reference
to header file :
#include "../../arch/arm/mach-at91/at91_aic.h"

Move arch/arm/mach-at91/irq.c to drivers/irqchip/irq-at91.c.
Move arch/arm/mach-at91/at91_aic.h to
arch/arm/mach-at91/include/mach/at91_aic.h to avoid ugly reference
to header file :
#include "../../arch/arm/mach-at91/at91_aic.h"
