regulator: Fix build warnings from regulator_can_change_voltage() Cut down on noise for mainstream users of the API and people doing build testing by dropping the deprecated flag from regulator_can_change_voltage() as it triggers even on the EXPORT_SYMBOL_GPL() which affects all builds rather than just the remaining drivers with calls to it (for which fixes are currently pending). The function remains deprecated and is expected to be removed entirely in v4.8.

gpio-v4.7-1d30a2b47 · ·
This is the bulk of GPIO changes for kernel cycle v4.7: Core infrastructural changes: - Support for natively single-ended GPIO driver stages. This means that if the hardware has registers to configure open drain or open source configuration, we use that rather than (as we did before) try to emulate it by switching the line to an input to get high impedance. This is also documented throughly in Documentation/gpio/driver.txt for those of you who did not understand one word of what I just wrote. - Start to do away with the unnecessarily complex and unitelligible ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from the time when the GPIO subsystem was unmaintained. Archs can now just select GPIOLIB and be done with it, cleanups to arches will trickle in for the next kernel. Some minor archs ACKed the changes immediately so these are included in this pull request. - Advancing the use of the data pointer inside the GPIO device for storing driver data by switching the PowerPC, Super-H Unicore and a few other subarches or subsystem drivers in ALSA SoC, Input, serial, SSB, staging etc to use it. - The initialization now reads the input/output state of the GPIO lines, so that each GPIO descriptor knows - if this callback is implemented - whether the line is input or output. This also reflects nicely in userspace "lsgpio". - It is now possible to name GPIO producer names, line names, from the device tree. (Platform data has been supported for a while.) I bet we will get a similar mechanism for ACPI one of those days. This makes is possible to get sensible producer names for e.g. GPIO rails in "lsgpio" in userspace. New drivers: - New driver for the Loongson1. - The XLP driver now supports Broadcom Vulcan ARM64. - The IT87 driver now supports IT8620 and IT8628. - The PCA953X driver now supports Galileo Gen2. Driver improvements: - MCP23S08 was switched to use the gpiolib irqchip helpers and now also suppors level-triggered interrupts. - 74x164 and RCAR now supports the .set_multiple() callback - AMDPT was converted to use generic GPIO. - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994 support the new single ended callback for open drain and in some cases open source. - Implement the .get_direction() callback for a few more drivers like PL061, Xgene. Cleanups: - Paul Gortmaker combed through the drivers and de-modularized those who are not really modules. - Move the GPIO poweroff DT bindings to the power subdir where they belong. - Rename gpio-generic.c to gpio-mmio.c, which is much more to the point. That's what it is handling, nothing more, nothing less.

ACPI material for v4.7-rc1 - In-kernel ACPICA code update to the upstream release 20160422 adding support for ACPI 6.1 along with some previously missing bits of ACPI 6.0 support, making a fair amount of fixes and cleanups and reducing divergences between the upstream ACPICA and the in-kernel code (Bob Moore, Lv Zheng, Al Stone, Aleksey Makarov, Will Miles). - ACPI Generic Event Device (GED) support and a fix for it (Sinan Kaya, Paul Gortmaker). - INT3406 thermal driver for display thermal management and ACPI backlight support code reorganization related to it (Aaron Lu, Arnd Bergmann). - Support for exporting the value returned by the _HRV (hardware revision) ACPI object via sysfs (Betty Dall). - Removal of the EXPERT dependency for ACPI on ARM64 (Mark Brown). - Rework of the handling of ACPI _OSI mechanism allowing the _OSI("Darwin") support to be overridden from the kernel command line among other things (Lv Zheng, Chen Yu). - Rework of the ACPI tables override mechanism to prepare it for the introduction of overlays support going forward (Lv Zheng, Rafael Wysocki). - Fixes related to the ECDT support and module-level execution of AML (Lv Zheng). - ACPI PCI interrupts management update to make it work better on ARM64 mostly (Sinan Kaya). - ACPI SRAT handling update to make the code process all entires in the table order regardless of the entry type (Lukasz Anaczkowski). - EFI power off support for full-hardware ACPI platforms that don't support ACPI S5 (Chen Yu). - Fixes and cleanups related to the ACPI core's sysfs interface (Dan Carpenter, Betty Dall). - acpi_dev_present() API rework to reduce possible confusion related to it (Lukas Wunner). - Removal of CLK_IS_ROOT from two ACPI drivers (Stephen Boyd). /

Power management material for v4.7-rc1 - New cpufreq "schedutil" governor (making decisions based on CPU utilization information provided by the scheduler and capable of switching CPU frequencies right away if the underlying driver supports that) and support for fast frequency switching in the acpi-cpufreq driver (Rafael Wysocki). - Consolidation of CPU frequency management on ARM platforms allowing them to get rid of some platform-specific boilerplate code if they are going to use the cpufreq-dt driver (Viresh Kumar, Finley Xiao, Marc Gonzalez). - Support for ACPI _PPC and CPU frequency limits in the intel_pstate driver (Srinivas Pandruvada). - Fixes and cleanups in the cpufreq core and generic governor code (Rafael Wysocki, Sai Gurrappadi). - intel_pstate driver optimizations and cleanups (Rafael Wysocki, Philippe Longepe, Chen Yu, Joe Perches). - cpufreq powernv driver fixes and cleanups (Akshay Adiga, Shilpasri Bhat). - cpufreq qoriq driver fixes and cleanups (Jia Hongtao). - ACPI cpufreq driver cleanups (Viresh Kumar). - Assorted cpufreq driver updates (Ashwin Chaugule, Geliang Tang, Javier Martinez Canillas, Paul Gortmaker, Sudeep Holla). - Assorted cpufreq fixes and cleanups (Joe Perches, Arnd Bergmann). - Fixes and cleanups in the OPP (Operating Performance Points) framework, mostly related to OPP sharing, and reorganization of OF-dependent code in it (Viresh Kumar, Arnd Bergmann, Sudeep Holla). - New "passive" governor for devfreq (for SoC subsystems that will rely on someone else for the management of their power resources) and consolidation of devfreq support for Exynos platforms, coding style and typo fixes for devfreq (Chanwoo Choi, MyungJoo Ham). - PM core fixes and cleanups, mostly to make it work better with the generic power domains (genpd) framework, and updates for that framework (Ulf Hansson, Thierry Reding, Colin Ian King). - Intel Broxton support for the intel_idle driver (Len Brown). - cpuidle core optimization and fix (Daniel Lezcano, Dave Gerlach). - ARM cpuidle cleanups (Jisheng Zhang). - Intel Kabylake support for the RAPL power capping driver (Jacob Pan). - AVS (Adaptive Voltage Switching) rockchip-io driver update (Heiko Stuebner). - Updates for the cpupower tool (Arjun Sreedharan, Colin Ian King, Mattia Dongili, Thomas Renninger). /

regulator: Updates for v4.7 A few core enhancements to deal with some of the slightly more complicated edge cases that have started cropping up in systems, both new ones and old ones that people started worrying about upstream, but otherwise a quiet release for the regulator API: - When applying constraints at system image if we have a voltage range specified and the regulator is currently configured outside the bounds of that range bring the regulator to the nearest end of the range. - When regulators are in non-regulating bypass modes make sure that we always use the voltage from the parent regulator. - Support for LP873x, PV88080, PM8894 and FAN53555 chips.

regulator: Fixes for v4.6 A small collection of driver specific fixes for the regulator subsysetem: - Fix handling of probe deferral for GPIO regulators. - Fix a typo in the module alias for DA9053. - Fix the definition of BUCK9 in the S2MPS11 driver. This change looks larger than it is because an irregularity in the hardware means that the macro used to define bucks 6-10 needs duplicating and tweaking to have a separate macro for 9. - Fix a series of errors in the definitions of the LDOs the AXP20x regulators, some of which had always been present and some of which were introduced in the merge window.

Some more work for 4.7, notably: * completion and fixups of nla_put_64_64bit() work * remove a/b/g/n from wext nickname to avoid confusion with 11ac (which wouldn't even fit fully there due to string length restrictions) along with some other minor changes/cleanups.
