From 0d93d8bb7f52190d76e9dba7f4561aabefaff34a Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Tue, 8 Dec 2009 16:34:26 -0700 Subject: [PATCH] OMAP: omap_device: track latency in nanoseconds Rather than having to do a usecs = nsecs / NSECS_PER_USEC to track latency in usecs, just track it in nanoseconds.
