Subject: [PATCH 13/40] ARM: s5pv310: update clock source registration
Date: Fri, 17 Dec 2010 11:39:44 +0000	[thread overview]
Message-ID: <E1PTYf2-0006iU-DY@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: 20101217113223.GC9937@n2100.arm.linux.org.uk

In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.
