Subject: [PATCH 00/10] ARM: S3C24XX: rework irq handling for a later dt usage
Date: Sun, 18 Nov 2012 01:51:00 +0100	[thread overview]
Message-ID: <201211180151.01029.heiko@sntech.de> (raw)

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 describing
its individual interrupts.

With this declarative approach it should also be (hopefully) easy to
move this to devicetree later.

For the initial transformation (in patch 1) I gave up on trying to do
this in individual steps, so the patch might be a bit bumpy to read,
but the new irq code does provide the exactly same interrupts and
handlers as the old code. This also means that the unconverted arches
shouldn't feel any difference at all.

I've only included the s3c2416 and s3c2443 interrupts for now, as the
s3c2416 is my main development platform and the s3c2443 is so very
similar. But the other arches use the same mechanics so conversion
should be quite easy later.

As it seems to be the policy for drivers/irqchip that drivers there
should not contain platform-hooks or pollute the namespace with custom
init functons, the irq code stays in plat-s3c24xx for now.
