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.
So, in order not to break those special drivers first patch renames ->target() to ->target_old() and the following patches will define the new prototype and convert existing drivers one by one.
There are 12 drivers after this patchset which still use the heavy weight version, i.e. target_old() and 39 drivers have adopted this new approach.
Once those 12 drivers are also moved to use .target(), .target_old() 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
After this patchset this is the diffstat for 107 patches: 54 files changed, 357 insertions(+), 1411 deletions(-)

This patch implements the new light weight prototype for target() routine. It looks like this:
int target(struct cpufreq_policy *policy, unsigned int index);
CPUFreq core will call cpufreq_frequency_table_target() before calling this routine and pass index to it.
This also marks target_old() interface as deprecated. So, that new drivers avoid using it.

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.
So, in order not to break those special drivers first patch renames ->target() to ->target_old() and the following patches will define the new prototype and convert existing drivers one by one.
Super-ugly.
Please just keep the old .target() as is, add a new callback and switch the suitable drivers to using it. You may call the new one .target_index() or something along these lines.
Thanks, Rafael

Thanks. I expected something similar.. :)

I thought of implementing with this name but then thought maybe earlier name is good enough and can be kept and so went for the *Super-ugly* solution..
Will be fixed :)
