[PATCH 14/13] clocksource: ARM sp804: allow clocksource name to be specified

Russell King - ARM Linux linux at arm.linux.org.uk
Thu May 12 09:49:24 EDT 2011


This allows platforms to specify the clocksource name upon
registration, which is necessary should they wish to register more
than one sp804 clocksource.
