2008-07-03	ARM: OMAP: DMTimer: Optimize by adding load and start	Richard Woodruff	1	-0/+1
	This patch optimizes the timer load and start sequence. By combining the load and start a needless posted wait can be removed from the system timer execution path. * Before patch register writes are taking up .078% @ 500MHz during idle.
