From e3a4fab0c0c30e21e104712f4e9cb39f175d0f21 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 11 Nov 2009 14:05:34 +0000 Subject: mips: Use generic mult/shift factor calculation for clocks Replace the MIPS functions of mult/shift factor calculation for clock events and clock sources with inline functions which call the generic functions. The minimum guaranteed conversion range is set to 4 seconds which corresponds to the current MIPS implementation.
