commit 935e93fcc022ff7be7046d2435ce6441e260abfb Author: Hauke Mehrtens <hauke@hauke-m.de> Date: Wed Sep 18 13:33:00 2013 +0200 MIPS: BCM47XX: Fix detected clock on Asus WL520GC and WL520GU The Asus WL520GC and WL520GU are based on the BCM5354 and clocked at 200MHz, but they do not have a clkfreq nvram variable set to the correct value. This adds a workaround for these devices.
