From 6cd82ffe0cd3836b32b29bd1436e5fd551957d54 Mon Sep 17 00:00:00 2001 From: Maurus Cuelenaere Date: Tue, 4 May 2010 13:12:32 +0200 Subject: [PATCH] ARM: SAMSUNG: Move HWMON from plat-s3c24xx to plat-samsung Move HWMON platform definition from plat-s3c24xx to plat-samsung and adjust mach-bast to use the new s3c_hwmon_set_platdata(). This allows usage of dev-hwmon by other Samsung SoCs.
