[PATCH V2 00/35] CPUFreq: Implement light weight ->target(): for 3.13

by Viresh Kumar

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/… 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 <andrew(a)lunn.ch> Cc: David S.

[PATCH 00/44] cpufreq: define generic routines for cpufreq drivers: for 3.13

by Viresh Kumar

Most of the CPUFreq drivers do similar things in .exit() and .verify() routines and .attr. So its better if we have generic routines for them which can be used by cpufreq drivers then. This patchset first fixes all existing drivers to do cpufreq_frequency_table_put_attr() corresponding to cpufreq_frequency_table_get_attr() and then create generic routines which will be used by most of the cpufreq drivers. This is rebased on Rafael's bleeding edge + some more cleanup work that I posted earlier: https://lkml.org/lkml/2013/8/8/263 This patchset and its dependencies are pushed here: https://git.linaro.org/gitweb?p=people/vireshk/linux.git;a=shortlog;h=refs/… @Rafael: You would be very happy to see the changelog :) 49 files changed, 287 insertions(+), 1215 deletions(-) Cc: Andrew Lunn <andrew(a)lunn.ch> Cc: David S.

[PATCH 00/37] CPUFreq: set policy->cur in cpufreq core instead of

by Viresh Kumar

Almost all drivers set policy->cur with current cpu frequency in their ->init() part. This can be done for all of them at core level and so they wouldn't need to do it. This patchset adds supporting code in cpufreq core for calling get() after we have called init() for a policy. Also fixes all drivers accordingly. These drivers were still doing some stuff which isn't required and was done by core already. And that is cleaned as well. This is Fourth part of my cleanup work for CPUFreq, first three are (And obviously its rebased over 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 3.

[PATCH 1/2] ARM: dts: Enable USB hub on Arndale

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The Arndale has a SMSC USB3503 connected in hardware only mode like a PHY, support it using the usb-nop-xceiv binding. Note that due to a regrettable decision to use a regulator to represent the reset signal this uses a fixed voltage regulator to do that, there is a plan to use the reset controller binding once that is merged so it does not seem worthwhile to fix the usb-nop-xceiv driver at this point.
