From dd89dd98cb9ae28f9e4c4d2c08be427a1f941c54 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Mon, 12 Nov 2007 23:24:04 -0800 Subject: [PATCH] ARM: OMAP: TimerMPU: Remove MPU-timer based sched_clock() Remove MPU-timer based sched_clock() in favor of the common one based on 32k sync timer which works across all OMAP1/2/3 platforms. Using 32k based one also gives a valid sched_clock() very early in the boot process.
