From e3659351da0976f47b2fa1c225ddaf411b9dbb51 Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Wed, 14 Sep 2016 16:26:53 -0700 Subject: [PATCH 1/3] Revert "ARM: dts: am335x-boneblack: Enable 1GHz OPP for cpu" This reverts commit c36e6ec904876de1935b1d74d2d711e6f5ceb572. The original commit updated the cpufreq operating points tables for am335x-boneblack 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.
