From 3d73710880afa3d61cf57b5d4eb192e812eb7e4f Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 28 Jun 2011 10:59:12 -0700 Subject: cpufreq: expose a cpufreq_quick_get_max routine This allows drivers and other code to get the max reported CPU frequency. Initial use is for scaling ring frequency with GPU frequency in the i915 driver.
