From 8db23f7df6be572d816f0d056fec16c954d3bdf6 Mon Sep 17 00:00:00 2001 From: Qingmin Liu Date: Wed, 7 Jan 2015 16:58:23 +0530 Subject: [PATCH] MIPS: Netlogic: Fix nlm_xlp2_get_pic_frequency to use ref_div The variable ref_div is initialized to the correct divisor but not used in the frequency calculation. This caused incorrect frequency to be reported when the clock divisor is not 3.
