This set of patches introduces AIC5 support with the goal to have only one
kernel image for all SOCs. That's why sparse irq support was added.
AIC5 can manage up to 128 irq lines. It introduces a new register map and
a source select register to select the IRQ line we want to configure.
v3 changes:
- of irq priorities support patch reworked: add a cell for priority value.
- sparse irq support patch reworked: no more using nr_irqs, so have to shift
static irq number by NR_IRQS_LEGACY.
v2 changes:
- add Jean-Christophe patches since my patches are based on abd there have
not been submitted yet
- I missed some machine descriptors in the first version, it
is corrected with this new one.
- correct sparse irq support and remove mach/irqs.h.
- correct issue on AIC5 support (missing allocation).

From: ludovic.desroches at atmel.com @ 2012-06-23 16:11 UTC (permalink / raw)
To: linux-arm-kernel
From: Ludovic Desroches <ludovic.desroches@atmel.com>
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.

mach/irqs only defines FIQ_START which doesn't appear to be used anywhere
so remove it.

From: Ludovic Desroches <ludovic.desroches@atmel.com>
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.

Thanks for this nice series.
I will queue it up in a at91-3.6-cleanup branch soon.

> Enable sparse irq support for multisoc image. It involves to add the

> 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.
