2012-10-24ARM: at91: fix external interrupts in non-DT caseNicolas Ferre
Management of external interrupts has changed but the non-DT code has not integrated these changes. Add a mask to pass external irq specification from SoC specific code to the at91_aic_init() function.

2012-07-04ARM: at91: fix new build errorsArnd Bergmann
MULTI_IRQ_HANDLER and SPARSE_IRQ are now required everywhere because mach/irqs.h and mach/entry-macros.S are gone but the symbols are only selected for AT91SAM9, not for the NOMMU parts. A few files now need to include linux/io.h directly, which used to be included through other headers that have changed. The new at91_aic_irq_priorities variable is only used with CONFIG_OF enabled and should not be visible otherwise.

2012-07-02ARM: at91: add AIC5 supportLudovic Desroches
The number of lines of AIC5 has increased from 32 to 128. Due to this increase, a source select register has been introduced for the interrupt line selection. Moreover, register mapping has been changed. For that reasons, we need some dedicated callbacks for AIC5. Power management is also concerned by these changes. On suspend, we can't get the whole interrupt mask register as before, we have to read this register 128 times. To reduce this overhead, a snapshot of the whole IMR is maintained.

2012-07-02ARM: at91: sparse irq supportLudovic Desroches
Enable sparse irq support for multisoc image. It involves to add the NR_IRQS_LEGACY offset to static SoC irq number definitions since NR_IRQS_LEGACY irq descs are allocated before AIC requests irq descs allocation. Move NR_AIC_IRQS macro to a more appropiate place with the purpose to remove mach/irqs.h later.

2012-07-02ARM: at91: at91 based machines specify their own irq handler at run timeLudovic Desroches

2012-07-02ARM: at91: aic can use fast eoi handler typeLudovic Desroches
The Advanced Interrupt Controller allows us to use the fast EOI handler type. It lets us remove the Atmel specific workaround into arch/arm/kernel/irq.c used to indicate to the AIC the end of the interrupt treatment.

2012-03-01ARM: at91: AIC and GPIO IRQ device tree initializationNicolas Ferre
Both AIC and GPIO controllers are now using the standard of_irq_init() function to initialize IRQs in case of DT use. The DT specific initialization functions are now separated from the non-DT case and are now using "linear" irq domains. The .map() irqdomain operation is responsible for positioning the IRQ handlers. In AIC case, the Linux IRQ number is directly programmed in the hardware to avoid an additional reverse mapping operation. The AIC position its irq domain as the "default" irq domain. For DT case, the priority is not yet filled in the SMR. It will be the subject of another patch. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2012-03-01ARM: at91/aic: add irq domain and device tree supportNicolas Ferre
Add an irqdomain for the AIC interrupt controller. The device tree support is mapping the registers and is using the irq_domain_add_legacy() to manage hwirq translation. The documentation is describing the meaning of the two cells required for using this "interrupt-controller" in a device tree node.

2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-02-08[ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor
Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
