[PATCH 1/2] mfd: wm8994-core: disable regulators before removing them

by Viresh Kumar

The order in which resources were freed in wm8994_device_exit() isn't correct. The regulators are removed before they are disabled. Fix it by reordering code a bit, which makes it exact opposite of wm8994_device_init() as well.

[PATCH V2 0/2] cpufreq: Upstream Android's Interactive governor

by Viresh Kumar

Hi Rafael et. al., We had some discussions [1] earlier on the PM mailing about upstreaming the cpufreq governor most widely used on Android Mobile phones and tablets: Interactive governor. People (including Rafael) mostly agreed that we better get it upstreamed and here is an attempt to upstream most of it (idle notifiers aren't included in this series). I picked the latest code spread over 70-80 patches from [2]. The unmodified code, based over mainline is pushed [4] for reference. I have updated the governor to align it with the current practices followed with mainline governors, like using utilization hooks from the scheduler and handling kobject (for governor's sysfs directory) in a race free manner. And of course this included general cleanup of the governor as well. This version is pushed here [3] for testing. The Android version of interactive governor also uses idle EXIT notifiers, but that code isn't part of this series and will be sent separately later. For people interested in looking at that, those are 3 minor patches on top of this series and are pushed here [5]. I haven't changed the core logic of the governor intentionally, as that rather requires more in-depth knowledge of the use case for which the optimizations have been done. So, we should do any such thing later on with new patches, so that people can fix regressions easily. I also haven't tried to change the userspace interface as that may have broken the userspace that already exists and uses this governor. This has been lightly tested on my Exynos board (dual ARM A15), where the governor gets inserted/removed multiple times, the sysfs files are all functional. The frequency gets changed with load, etc. Amit Pundir (Linaro) has done extensive testing with Android and compared results of both Original Interactive governor and the modified one (in this series) and found them to be comparable. This series is based of pm/bleeding-edge branch. V1->V2: - Changes to fix compilation issues with latest mainline - Timer APIs got updated - s/mod_timer_pinned/mod_timer - s/init_timer/init_timer_pinned - Updated prototypes of cpufreq_frequency_table_target() and update_util_handler() -- viresh [1] http://marc.info/?l=linux-pm&m=146301864519072 [2] https://android.googlesource.com/kernel/common remotes/android/android-4.4 [3] git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/interactive [4] git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/interactive-orig [5] git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/intearctive-idle-notifier Viresh Kumar (2): cpufreq: Move gov_attr_* macros to cpufreq.h cpufreq: Add android's 'interactive' governor Documentation/cpu-freq/governors.txt | 86 ++ drivers/cpufreq/Kconfig | 30 + drivers/cpufreq/Makefile | 1 + drivers/cpufreq/cpufreq_governor.h | 8 - drivers/cpufreq/cpufreq_interactive.c | 1363 ++++++++++++++++++++++++++++ include/linux/cpufreq.h | 12 + include/trace/events/cpufreq_interactive.h | 112 +++ kernel/sched/cpufreq_schedutil.c | 8 +- 8 files changed, 1608 insertions(+), 12 deletions(-) create mode 100644 drivers/cpufreq/cpufreq_interactive.c create mode 100644 include/trace/events/cpufreq_interactive.h -- 2.7.1.410.g6faf27b

[PATCH 1/3] cpufreq: dt: Remove unused code

by Viresh Kumar

This is leftover from an earlier patch which removed the usage of platform data but forgot to remove this line. Remove it now.
