From e1d5c93e82eadd814949c023d0b16aa8fa8ad7ae Mon Sep 17 00:00:00 2001 From: Banajit Goswami Date: Wed, 19 May 2010 15:42:29 +0900 Subject: ARM: SAMSUNG: Move WDT device definitions in plat-samsung This patch moves the definitions of watchdog timer device from plat-s3c24xx to plat-samsung. This will enable all Samsung S3C and S5P series SoC's to use common WDT device definition.
