* irqchip/atmel-aic: Change return type of aic_common_set_priority()Milo Kim2016-02-081-3/+2
| | | | | | | | | | | | | | Priority validation is not necessary because aic_common_irq_domain_xlate() already handles it. With this removal, return type can be changed to void.

* irqchip/atmel-aic: Handle aic_common_irq_fixup in aic_common_of_initMilo Kim2016-02-081-3/+1
| | | | | | | | | | | | | | | AIC IRQ fixup is handled in each IRQ chip driver. It can be moved into aic_common_of_init() before returning the result. Then, aic_common_irq_fixup() can be changed to static type.

* irqchip: Appropriate __init annotation for const dataNicolas Pitre2015-07-271-1/+1
| | | | | | | | | | | | | | 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.

* irqchip: Prepare for local stub header removalJoel Porquet2015-07-111-1/+1
| | | | | | | | | | | | | | | | | 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.

* | genirq: Generic chip: Change irq_reg_{readl,writel} argumentsKevin Cernekee2014-11-091-20/+20
|/ | | | | | | | | | | | | | | | | | | | | 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.

* irqchip: atmel-aic: Add atmel AIC/AIC5 driversBoris BREZILLON2014-07-171-0/+247
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.
