+commit 0388a0410d590a6c239c1cfaa7d49bffd4ed1101

+
+    MIPS: BCM47XX: Fix clock detection for BCM5354 with 200MHz clock
+    
+    Some BCM5354 SoCs are running at 200MHz, but it is not possible to read
+    the clock from a register like it is done on some other SoC in ssb and
+    bcma. These devices should have a clkfreq nvram configuration value set
+    to 200, read it and set the clock to the correct value.

+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.
