25963dbd07 irqchip: atmel-aic: Add missing entry for rm9200 irq fixups 
The at91rm9200 have an RTT block and thus must at91rm9200_aic_irq_fixup
has to be called when initializing the irqchip.

624cba5726 irqchip: atmel-aic: Rename at91sam9_aic_irq_fixup for naming consistency 
Rename at91sam9_aic_irq_fixup into at91rm9200_aic_irq_fixup to be
consistent with other fixup functions.

f3b7bf1bd7 irqchip: atmel-aic: Add specific irq fixup function for sam9g45 and sam9rl 
The at91sam9g45 and at91sam9rl SoCs embed one RTT (Real Time Timer) and one
RTC block and thus need to call both rtt and rtc fixup functions.

ae25eac251 irqchip: atmel-aic: Add irq fixups for at91sam926x SoCs 
The at91sam9260, at91sam9261, at91sam9263 and at91sam9g20 embed an RTT
(Real Time Timer) block and thus need to call the aic_common_rtt_irq_fixup
function.

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.
