This patch moves the irq numbers starting with EINT4 4 points down to

For most S3C24XX architectures this will simply create 4 additional unused

This series is meant to go on top of the recent basic integration of the

After this everything is handled using the new structure.

In the past level irqs provided a special ack handler that also masked
the interrupt. But handle_level_irq also does mask-ack the interrupt
itself, so there is no need to keep this special ack function around.
We therefore can simplyfy the number of irq-chips again.

Hi Alexander,
I think this patch needs a bit more love :-) .
Please run scripts/checkpatch.pl on it and fix all the reported problems.
And I'd change the comment to something like:
/*
* S3C2443 CPU has a problem with EXTINTn registers.
* Essentially register-reads return transformed data, but

This adds a board file and the devicetree source files to support boards
using the Samsung S3C2416 SoC.
The dt source files contain the definitions generic to all S3C24XX SoCs
in the s3c24xx.dtsi file which then gets extendes with S3C2416 specific
definitions.

This adds devicetree parsing of the controller-data for the
interrupt controllers on S3C24XX architectures.

This series builts on my not-yet-accepted irq rework and provides the
last bits to use devicetree on s3c2416 boards. It also requires the
patch "serial: samsung: add devicetree properties for non-Exynos SoCs"
which adds the missing device names to the mapping table.
Thanks to the work of other dev

c2416 cpufreq driver also on
the s3c2443, as the armdiv etc structure is the same.

wow ...
Hi Alexander,
first of all could you elaborate a bit more on the error you experience,
because I currently have problems to understand it from the code alone :-) .
More inline.

The contents of the base irq-register are shared between the s3c2443
and s3c2416/s3c2450.

Previously the irq init used s3c24xx_init_irq and an additional
arch_initcall to add the cpu specific irqs.
To be able to simplyfy the irq init later, create a new function
s3c2443_init_irq, which then calls s3c24xx_init_irq but also adds
the cpu specific irqs.

The contents of the base interrupt register is identical for
s3c2443 and s3c2416/2450, so keep it separate already.

This is needed to further clean up the irq init.
The only change made during the move is the renaming of the
possibly conflicting irq_save to irq2_save

This patch integrates the irq-pm functions we moved in the previous patch.
This includes some static attributes and the removal of the irq suspend

With this change, it's possible to make more elements static
and also reduce the number of .h elements further down the road.

The irqs available on the machine and even the bit settings in the
irq registers differ a lot through all the s3c24xx subarchitectures.
This results in each subarch having its own irq init which adds its
specific irqs to the base ones created in plat-s3c24xx/irq.c.
This of course makes a future mo
All S3C24XX arches share the same interrupt registers and basic handling
principles but the individual interrupts differ quite a lot between all
the arches.
This series therefore tries to unify this a bit by abstracting the irq
handling and enabling the arches to simply provide a structure describ
