From 652ed95d5fa6074b3c4ea245deb0691f1acb6656 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 9 Jan 2014 20:38:43 +0530 Subject: cpufreq: introduce cpufreq_generic_get() routine CPUFreq drivers that use clock frameworks interface,i.e. clk_get_rate(), to get CPUs clk rate, have similar sort of code used in most of them. This patch adds a generic ->get() which will do the same thing for them. All those drivers are required to now is to set .get to cpufreq_generic_get() and set their clk pointer in policy->clk during ->init().
