cover ARM: at91: introduce AIC5 support

Hi,

This set of patches introduces AIC5 support with the goal to have only one kernel image for all SOCs.
AIC5 can manage up to 128 irq lines and introduces a new register map and a source select register to select the IRQ line we want to configure.

Regards

Ludovic

PATCH 1/4 ARM: at91: at91 based machines specify their own irq handler at run time

From: Ludovic Desroches <[email protected]>

SOC_AT91SAM9 selects MULTI_IRQ_HANDLER in order to let machines specify their own IRQ handler at run time.

At least these board files contain more than one MACHINE_START, but you only update the last one. Same for the third patch.

I have not looked at the rest of the patch.

Thanks for your feedback, I'll correct it in V2.

PATCH 2/4 ARM: at91: fix irq_alloc_descs parameters for sparse irq

In reply to ludovic.desroches at atmel.com

From: Ludovic Desroches <[email protected]>

When SPARSE_IRQ is enabled, all NR_IRQS or mach_desc->nr_irqs will be allocated by arch_probe_nr_irqs(). This caused irq_alloc_descs to allocate irq_descs after the pre-allocated space. Make irq_alloc_descs search for an exact irq range in order to get an error when it has been pre-allocated.

PATCH 3/4 ARM: at91: enable use of sparse irq

In reply to ludovic.desroches at atmel.com

From: Ludovic Desroches <[email protected]>

If we want to have one kernel for all atmel SOCs, nr_irqs has to be set at runtime since the number of irqs managed by AIC depends on its version.

PATCH 4/4 ARM: at91: add AIC5 support

In reply to ludovic.desroches at atmel.com

From: Ludovic Desroches <[email protected]>

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.
