Subject: [PATCH 2/5 v2] Add samsung-time support for s3c24xx
Date: Sun, 02 Dec 2012 20:44:09 +0100 [thread overview]
Message-ID: <50BBAF89.4010006@openwide.fr> (raw)
In-Reply-To: <201211280057.16345.heiko@sntech.de>
This patch replace ARCH_USES_GETTIMEOFFSET by GENERIC_CLOCKEVENTS for s3c24xx devices.
It becomes possible to use the high-resolution timer and dynamic ticks.
