Merge branch 'next/irq-s3c24xx' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup
From Kukjin Kim: This is redoing the s3c24xx irqs in a generic way by using a declarative approach. * 'next/irq-s3c24xx' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: S3C24XX: transform s3c2443 subirqs into new structure ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs ARM: S3C24XX: move s3c2443 irq code to irq.c ARM: S3C24XX: transform s3c2416 irqs into new structure ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs ARM: S3C24XX: move s3c2416 irq init to common irq code ARM: S3C24XX: Modify s3c_irq_wake to use the hwirq property ARM: S3C24XX: Move irq syscore-ops to irq-pm ARM: S3C24XX: transform irq handling into a declarative form Signed-off-by: Olof Johansson <olof@lixom.net>
