From 59a8c10b253358bebb263540e7ad67e986d66277 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 28 Aug 2013 10:41:45 +0200 Subject: MIPS: ath79: Use ath79_get_sys_clk_rate to get basic clock rates Instead of accessing the rate field of the static clock devices directly, use the recently introduced helper function to get the rate of the basic clocks. The static ath79_{ahb,cpu,ddr,ref}_clk variables will be removed by a subsequent patch. The actual change is in preparation of that. Also move the clock frequency printing code into the plat_time_init function. We are getting the cpu clock rate there already so we can save an extra call of the helper.
