git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32 Pull AVR32 removal from Hans-Christian Noren Egtvedt: "This will remove support for AVR32 architecture from the kernel and clean away the most obvious architecture related parts. Removing dead code in drivers is the next step" Notes from previous discussion about this: "The AVR32 architecture is not keeping up with the development of the kernel, and since it shares so much of the drivers with Atmel ARM SoC, it is starting to hinder these drivers to develop swiftly. Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now Microchip). Finally, the GCC toolchain is stuck at version 4.2.x, and has not received any patches since the last release from Atmel; 4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this toolchain is no longer able to properly link the network stack. Haavard and I have came to the conclusion that we feel keeping AVR32 on life support offers more obstacles for Atmel ARMs, than it gives joy to AVR32 users. I also suspect there are very few AVR32 users left today, if anybody at all" That discussion was acked by Andy Shevchenko, Boris Brezillon, Nicolas Ferre, and Haavard Skinnemoen. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32: mm: remove AVR32 arch special handling in mm/Kconfig lib: remove check for AVR32 arch in test_user_copy lib: remove AVR32 entry in Kconfig.debug compile with frame pointers scripts: remove AVR32 support from checkstack.pl docs: remove all references to AVR32 architecture avr32: remove support for AVR32 architecture

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "These are some device enumeration code changes, updates of the AC and battery drivers to help them avoid attaching to devices that cannot be handled by them, new operation region driver for the Intel CHT Whiskey Cove PMIC, new sysfs entries for CPPC performance capabilities, a new _REV quirk blacklist entry and a couple of assorted minor fixes and cleanups. Specifics: - Update the core device enumeration code to make it more internally consistent and robust and drop the force_remove sysfs attribute that could be used to tell it to ignore errors on device hot-removal which was dangerous in general and no real and still relevant use cases for it could be found (Rafael Wysocki, Michal Hocko). - Make the core device enumeration code use _PXM to associate platform devices created by it with specific NUMA nodes (Shanker Donthineni). - Extend the CPPC library by adding more sysfs entries for performance capabilities to it and making it use the lowest nonlinear performance parameter (Prashanth Prakash). - Make the CPU online more consistent with CPU initialization in the ACPI processor driver (Prashanth Prakash). - Update the AC and battery drivers to help them avoid attaching to devices that cannot be handled by them and update the axp288_charger power supply driver to work correctly on ACPI systems without the INT3496 device (Hans de Goede). - Add an ACPI operation region driver for the Intel CHT Whiskey Cove PMIC and update the xpower operation region driver to work without IIO which isn't really necessary for it to work (Hans de Goede). - Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist (Kai Heng Feng). - Make the code in the ACPI video driver easier to follow by adding symbols and comments to it (Dmitry Frank). - Update ACPI documentation and drop a function that has no users from the tables-handling code (Cao jin, Baoquan He)" * tag 'acpi-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / PMIC: Stop xpower OPRegion handler relying on IIO ACPI / PMIC: Add opregion driver for Intel CHT Whiskey Cove PMIC ACPI / scan: Avoid enumerating devices more than once ACPI / scan: Apply default enumeration to devices with ACPI drivers power: supply: axp288_charger: Only wait for INT3496 device if present ACPI / AC: Add a blacklist with PMIC ACPI HIDs with a native charger driver ACPI / battery: Add a blacklist with PMIC ACPI HIDs with a native battery driver ACPI / battery: Fix acpi_battery_exit on acpi_battery_init_async errors ACPI / utils: Add new acpi_dev_present helper ACPI / video: add comments about subtle cases ACPI / video: get rid of magic numbers and use enum instead ACPI / doc: linuxized-acpica.txt: fix typos ACPI / blacklist: add _REV quirk for Dell Inspiron 7537 ACPI / tables: Drop acpi_parse_entries() which is not used ACPI / CPPC: add sysfs entries for CPPC perf capabilities ACPI / CPPC: Read lowest nonlinear perf in cppc_get_perf_caps() ACPI / platform: Update platform device NUMA node based on _PXM method ACPI / Processor: Drop setup_max_cpus check from acpi_processor_add() ACPI / scan: Drop support for force_remove

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "This time the majority of changes go to the cpufreq subsystem (and to the intel_pstate driver in particular) and there are some updates in the generic power domains framework, cpuidle, tools and a couple of other places. One thing worth mentioning is that the intel_pstate's sysfs interface has been reworked to be more consistent with the general expectations of the cpufreq core and less confusing, hopefully for the better. Also, we have a new cpufreq driver for Tegra186 and new hardware support in intel_pstata and the Mediatek cpufreq driver. Apart from that, the AnalyzeSuspend utility for system suspend profiling gets a companion called AnalyzeBoot for the analogous profiling of system boot and they both go into one place under tools/power/pm-graph/. The rest is mostly fixes, cleanups and code reorganization. Specifics: - Rework the intel_pstate driver's sysfs interface to make it more straightforward and more intuitive (Rafael Wysocki). - Make intel_pstate support all processors which advertise HWP (hardware-managed P-states) to the kernel in all operation modes and make it use the load-based P-state selection algorithm on a wider range of systems in the active mode (Rafael Wysocki). - Add cpufreq driver for Tegra186 (Mikko Perttunen). - Add support for Gemini Lake SoCs to intel_pstate (David Box). - Add support for MT8176 and MT817x to the Mediatek cpufreq driver and clean up that driver a bit (Daniel Kurtz). - Clean up intel_pstate and optimize it slightly (Rafael Wysocki). - Update the schedutil cpufreq governor, mostly to fix a couple of issues with it related to specific workloads, and rework its sysfs tunable and initialization a bit (Rafael Wysocki, Viresh Kumar). - Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers (Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar, YuanTian Tang). - Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert Uytterhoeven). - Add support for "always on" power domains to the genpd (generic power domains) framework and clean up that code somewhat (Ulf Hansson, Lina Iyer, Viresh Kumar). - Fix minor issues in the powernv cpuidle driver and clean it up (Anton Blanchard, Gautham Shenoy). - Move the AnalyzeSuspend utility under tools/power/pm-graph/ and add an analogous boot-profiling utility called AnalyzeBoot to it (Todd Brandt). - Add rk3328 support to the rockchip-io AVS (Adaptive Voltage Scaling) driver (David Wu). - Fix minor issues in the cpuidle core, the intel_pstate_tracer utility, the devfreq framework and the PM core documentation (Chanwoo Choi, Doug Smythies, Johan Hovold, Marcin Nowakowski)" * tag 'pm-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (56 commits) PM / runtime: Document autosuspend-helper side effects PM / runtime: Fix autosuspend documentation tools: power: pm-graph: Package makefile and man pages tools: power: pm-graph: AnalyzeBoot v2.0 tools: power: pm-graph: AnalyzeSuspend v4.6 cpufreq: Add Tegra186 cpufreq driver cpufreq: imx6q: Fix error handling code cpufreq: imx6q: Set max suspend_freq to avoid changes during suspend cpufreq: imx6q: Fix handling EPROBE_DEFER from regulator cpuidle: powernv: Avoid a branch in the core snooze_loop() loop cpuidle: powernv: Don't continually set thread priority in snooze_loop() cpuidle: powernv: Don't bounce between low and very low thread priority cpuidle: cpuidle-cps: remove unused variable tools/power/x86/intel_pstate_tracer: Adjust directory ownership cpufreq: schedutil: Use policy-dependent transition delays cpufreq: schedutil: Reduce frequencies slower PM / devfreq: Move struct devfreq_governor to devfreq directory PM / Domains: Ignore domain-idle-states that are not compatible cpufreq: intel_pstate: Add support for Gemini Lake powernv-cpuidle: Validate DT property array size ...

2017-05-01Merge branch 'for-4.12/block' of git://git.kernel.dk/linux-blockLinus Torvalds7-97/+576
Pull block layer updates from Jens Axboe: - Add BFQ IO scheduler under the new blk-mq scheduling framework. BFQ was initially a fork of CFQ, but subsequently changed to implement fairness based on B-WF2Q+, a modified variant of WF2Q. BFQ is meant to be used on desktop type single drives, providing good fairness. From Paolo. - Add Kyber IO scheduler. This is a full multiqueue aware scheduler, using a scalable token based algorithm that throttles IO based on live completion IO stats, similary to blk-wbt. From Omar. - A series from Jan, moving users to separately allocated backing devices. This continues the work of separating backing device life times, solving various problems with hot removal. - A series of updates for lightnvm, mostly from Javier. Includes a 'pblk' target that exposes an open channel SSD as a physical block device. - A series of fixes and improvements for nbd from Josef. - A series from Omar, removing queue sharing between devices on mostly legacy drivers. This helps us clean up other bits, if we know that a queue only has a single device backing. This has been overdue for more than a decade. - Fixes for the blk-stats, and improvements to unify the stats and user windows. This both improves blk-wbt, and enables other users to register a need to receive IO stats for a device. From Omar. - blk-throttle improvements from Shaohua. This provides a scalable framework for implementing scalable priotization - particularly for blk-mq, but applicable to any type of block device. The interface is marked experimental for now. - Bucketized IO stats for IO polling from Stephen Bates. This improves efficiency of polled workloads in the presence of mixed block size IO. - A few fixes for opal, from Scott. - A few pulls for NVMe, including a lot of fixes for NVMe-over-fabrics. From a variety of folks, mostly Sagi and James Smart. - A series from Bart, improving our exposed info and capabilities from the blk-mq debugfs support. - A series from Christoph, cleaning up how handle WRITE_ZEROES. - A series from Christoph, cleaning up the block layer handling of how we track errors in a request. On top of being a nice cleanup, it also shrinks the size of struct request a bit. - Removal of mg_disk and hd (sorry Linus) by Christoph. The former was never used by platforms, and the latter has outlived it's usefulness. - Various little bug fixes and cleanups from a wide variety of folks. * 'for-4.12/block' of git://git.kernel.dk/linux-block: (329 commits) block: hide badblocks attribute by default blk-mq: unify hctx delay_work and run_work block: add kblock_mod_delayed_work_on() blk-mq: unify hctx delayed_run_work and run_work nbd: fix use after free on module unload MAINTAINERS: bfq: Add Paolo as maintainer for the BFQ I/O scheduler blk-mq-sched: alloate reserved tags out of normal pool mtip32xx: use runtime tag to initialize command header scsi: Implement blk_mq_ops.show_rq() blk-mq: Add blk_mq_ops.show_rq() blk-mq: Show operation, cmd_flags and rq_flags names blk-mq: Make blk_flags_show() callers append a newline character blk-mq: Move the "state" debugfs attribute one level down blk-mq: Unregister debugfs attributes earlier blk-mq: Only unregister hctxs for which registration succeeded blk-mq-debugfs: Rename functions for registering and unregistering the mq directory blk-mq: Let blk_mq_debugfs_register() look up the queue name blk-mq: Register <dev>/queue/mq after having registered <dev>/queue ide-pm: always pass 0 error to ide_complete_rq in ide_do_devset ide-pm: always pass 0 error to __blk_end_request_all ..

2017-04-27mfd: exynos-lpass: Add support for clocksMarek Szyprowski1-0/+6
Exynos LPASS requires some clocks to be enabled to make any access to its registers. This patch adds code for handling such clocks. For current set of registers it is enough to keep sfr0_ctrl clock enabled. Till now it worked only because those clocks were enabled by bootloader and driver probe() happened before they were disabled by clock core because of lack of users. Handling those clocks is also needed to make it possible to enable support for audio power domain. This patch requires adding sfr0_ctrl clock to device tree.
