Merge branch 'next/irq-s3c24xx' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers

Browse Source 
From Kukjin Kim <kgene.kim@samsung.com>:

Here is finish the irq rework for s3c2412, s3c2440 and s3c2442 into the new
structure and eint0 to 3 on the s3c2412.

* 'next/irq-s3c24xx' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  gpio: samsung: fixes build warning with s3c2410_defconfig
  ARM: S3C24XX: handle s3c2412 eints using new infrastructure
  ARM: S3C24XX: add soc_is_s3c2412 option
  ARM: S3C24XX: include first 4 bits of the eint register in irq mapping
  ARM: S3C24XX: transform s3c2412 irqs into new structure
  ARM: S3C24XX: modify s3c2412 irq init to initialize all irqs
  ARM: S3C24XX: move s3c2412 irq init to common code
  ARM: S3C24XX: use samsung_sync_wakemask in s3c2412 pm
  ARM: S3C24XX: transform s3c2440 irqs into new structure
  ARM: S3C24XX: transform s3c2442 irqs into new structure
  ARM: S3C24XX: integrate s3c2440 irqs into common init
  ARM: S3C24XX: move s3c2440 irqs to common irq code
  ARM: S3C24XX: create dedicated irq init functions for s3c2440 and s3c2442
  ARM: S3C24XX: move s3c244x irq init to common irq code
