From c9b870e7e796eea515a261a314917317ebb1cb4a Mon Sep 17 00:00:00 2001 From: Byungho Min Date: Tue, 23 Jun 2009 21:40:03 +0900 Subject: ARM: S5PC100: IRQ and timer S5PC100 has 3 VICs(Vectored Interrupt Controller). The VICs come from S3C64xx series, so the driver source code can be shared with S3C families. The S5PC100 has 3 VICs while S3C64xx has only 2.
