ARM: S3C24XX: create dedicated irq init functions for s3c2440 and s3c2442
From: Heiko Stuebner <heiko@...> Date: Mon, 4 Feb 2013 13:44:39 +0100
Commit-Message
s3c2440 and s3c2442 need separate init functions, as the s3c2440 contains even more differing irqs that will be moved in the following patch. Signed-off-by: Heiko Stuebner <heiko@...>
