From 0f416d1317dd4ef9d758ddc3e13cde23aa909c2d Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Wed, 14 Sep 2016 16:26:53 -0700 Subject: Revert "ARM: dts: am33xx: Move to operating-points-v2 table and ti-cpufreq driver" This reverts commit 4317be1162108bcdf50dc53dfb48eac94dcff25c. The original commit updated the cpufreq operating points tables for am33xx but was merged before the driver making use of the node was merged, which breaks the existing cpufreq implementation on the system, so revert the patch until the ti-cpufreq driver is merged.
