[RFC PATCH v2 00/10] ARM: at91: move aic driver to drivers/irqchips

[Boris BREZILLON]

Hello,

This series is a proposal to move AIC driver to the irqchip directory.

It also changes the implementation design of the interrupt controller in
several ways:
 - make use of the generic chip framework whenever possible
 - add support for irq muxing definition to prevent spurious interrupts
   during system startup (see https://lkml.org/lkml/2013/3/8/175)
 - only support dt enabled boards


Best Regards,

Boris

Changes since v1:
 - rework the irq-mux bindings

Boris BREZILLON (10):
  genirq: generic chip: export irq_map_generic_chip function
  irqchip: atmel-aic: add new atmel AIC driver
  ARM: at91: introduce OLD_IRQ_AT91 Kconfig option
  ARM: at91: enclose at91_aic_xx calls in
    IS_ENABLED(CONFIG_OLD_IRQ_AT91) blocks
  ARM: at91: make use of the new AIC driver for dt enabled boards
  irqchip: atmel-aic: move binding doc to interrupt-controller
    directory
  irqchip: atmel-aic: document new dt properties and children nodes
  ARM: at91: remove old irq material
  ARM: at91/dt: add new AIC irq mux definitions for sam9x5 SoCs
  ARM: at91/dt: add new AIC irq mux definitions for sama5 SoCs
