Subject: [PATCH V2 15/35] cpufreq: imx6q: Covert to light weight ->target_index() routine
Date: Tue, 13 Aug 2013 19:02:28 +0530 [thread overview]
Message-ID: <217701887d98cb7b71b91a095c9ca30cb35d95b4.1376392602.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1376392602.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1376392602.git.viresh.kumar@linaro.org>
This patch converts existing .target() to newly defined light weight
.target_index() routine for this driver.
CPUFreq core will call cpufreq_frequency_table_target() before calling this
routine and will pass index to it.
