From 8eae19ccaeb5f519fc413c9646398a77dfbfa201 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Wed, 18 Sep 2013 13:33:00 +0200 Subject: 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.
