From mboxrd@z Thu Jan 1 00:00:00 1970 From: viresh.kumar@linaro.org (Viresh Kumar) Date: Tue, 13 Aug 2013 19:01:40 +0530 Subject: [PATCH V2 00/35] CPUFreq: Implement light weight ->target(): for 3.13 In-Reply-To: References: Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Currently prototype of cpufreq_drivers target routines is: int target(struct cpufreq_policy *policy, unsigned int target_freq, unsigned int relation); And most of the drivers call cpufreq_frequency_table_target() to get a valid index of their frequency table which is closest to the target_freq. And they don't use target_freq and relation after it. So, it makes sense to just do this work in cpufreq core before calling cpufreq_frequency_table_target() and simply pass index instead. But this can be done only with drivers which expose their frequency table with cpufreq core. For others we need to stick with the old prototype of target() until those drivers are converted to expose frequency tables. There are 7 drivers after this patchset which still use the heavy weight version, i.e. target() and 44 drivers have adopted this new approach, i.e. target_index(). Once those 7 drivers are also moved to use .target_index(), .target() will be removed completely. This is part 3 of my generic cpufreq cleanup stuff.. First two are posted here and this one is rebased of them: 1: cpufreq: Introduce cpufreq_table_validate_and_show() https://lkml.org/lkml/2013/8/8/263 2: cpufreq: define generic routines for cpufreq drivers https://lkml.org/lkml/2013/8/10/48 All these are pushed here: https://git.linaro.org/gitweb?p=people/vireshk/linux.git;a=shortlog;h=refs/heads/for-v3.13 V1->V2: ------ - Must be less ugly this time :) - new interface is named as target_index() instead of target() - old interface is kept as target() instead of target_old() - few more drivers got converted to use this infrastructure (5) - Documentation updates - CONFIG_CPU_FREQ_TABLE removed completely as core depends on it now Cc: Andrew Lunn Cc: David S.
