From: Greg Kroah-Hartman
Date: Fri Jun 19 2015 - 16:49:51 EST


4.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit ebb9bf18636926d5da97136c22e882c5d91fda73 upstream.

This reverts commit 7fe04d6fa824ccea704535a597dc417c8687f990.

Fixes some systems at the expense of others. Need to properly
fix the pll divider selection.
