From 2310780244d5c3b6cc843d4cc0b63332016678a0 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 28 Aug 2013 10:41:44 +0200 Subject: MIPS: ath79: Use a helper function to get system clock rates The ath79 platform uses similar code to get the rate of various clocks during init. Separate the similar code into a new helper function and use that to avoid code duplication.
