c376023b70 irqchip: Appropriate __init annotation for const data
Init data marked const should be annotated with __initconst for
correctness and not __initdata.  And for those already __initconst,
they should be qualified as const at the compiler level too.
This also fixes LTO builds that otherwise fail with section mismatch
errors.

41a83e06e2 irqchip: Prepare for local stub header removal
The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
the local irqchip.h became an empty shell, which solely includes
include/linux/irqchip.h

Include the global header in all irqchip drivers instead of the local
header, so we can remove it.

332fd7c4fe genirq: Generic chip: Change irq_reg_{readl,writel} arguments
Pass in the irq_chip_generic struct so we can use different readl/writel
settings for each irqchip driver, when appropriate.  Compute
(gc->reg_base + reg_offset) in the helper function because this is pretty
much what all callers want to do anyway.

Compile-tested using the following configurations:

    at91_dt_defconfig (CONFIG_ATMEL_AIC_IRQ=y)
    sama5_defconfig (CONFIG_ATMEL_AIC5_IRQ=y)
    sunxi_defconfig (CONFIG_ARCH_SUNXI=y)

tb10x (ARC) is untested.

6704d12d68 irqchip: atmel-aic: Define irq fixups for atmel SoCs
Define SoCs that need irq fixups before enabling the AIC irqchip.

At the moment we're only fixing irq generated by the RTC block, but other
fixups will be added later on.

b1479ebb77 irqchip: atmel-aic: Add atmel AIC/AIC5 drivers
Add AIC (Advanced Interrupt Controller) and AIC5 (AIC5 is an evolution of
the AIC block) drivers.
Put common code in irq-atmel-aic-common.c/.h so that both driver can access
shared functions (this will ease maintenance).

These drivers are only compatible with dt enabled board and replace the
old implementation found in arch/arm/mach-at91/irq.c.
