[PATCH v4 0/7] ARM: at91: move aic driver to drivers/irqchips

Hello,

This series moves the AIC driver to the irqchip directory and make use of
the generic chip framework whenever possible.

This driver only support DT boards (all legacy board files should be soon
replaced by their DT versions).

Since the last version AIC and AIC5 code have been split and common
functions have been moved to irq-atmel-aic-common.c.
I know there is not much code in this file and it could have been
duplicated in AIC and AIC5 drivers, but I'm planning to add more common
stuff soon (AIC irq fixups previously done in
arch/arm/mach-at91/sysirq_mask.c).

Jason, if everybody is fine with this version could you share a topic
branch  containing patch 1 to 3 with Nicolas ?

Thanks.

Best Regards,

Boris

Changes since v3:
 - split AIC and AIC5 code

Changes since v2:
 - remove irq line muxing definition
 - rework Kconfig options

Changes since v1:
 - rework the irq-mux bindings
