2017-04-14power: supply: cpcap-charger: Add minimal CPCAP PMIC battery chargerTony Lindgren
The custom CPCAP PMIC used on Motorola phones such as Droid 4 has a USB battery charger. It can optionally also have a companion chip that is used for wireless charging. The charger on CPCAP also can feed VBUS for the USB host mode. This can be handled by the existing kernel phy_companion interface.

2017-04-14power: supply: bq24190_charger: Use extcon to determine ilimit, 5v boostHans de Goede
Add support for monitoring an extcon device with USB SDP/CDP/DCP and HOST cables and adjust ilimit and enable/disable the 5V boost converter accordingly. This is necessary on systems where the PSEL pin is hardwired high and ILIM needs to be set by software based on the detected charger type, as well as on systems where the 5V boost converter is used, as that always needs to be enabled from software.

2017-04-14power: supply: bq24190_charger: Add support for bq24192iHans de Goede
The bq24192 and bq24192i are mostly identical to the bq24190, TI even published a single datasheet for all 3 of them. The difference between the bq24190 and bq24192[i] is the way charger-type detection is done, the bq24190 is to be directly connected to the USB a/b lines, where as the the bq24192[i] has a gpio which should be driven high/low externally depending on the type of charger connected, from a register level access pov there is no difference. The differences between the bq24192 and bq24192i are: 1) Lower default charge rate on the bq24192i 2) Pre-charge-current can be max 640 mA on the bq24192i On x86/ACPI systems the code which instantiates the i2c client may not know the exact variant being used, so instead of coding the model-id in the i2c_id struct and bailing if it does not match, check the reported model-id matches one of the supported variants. This commit only adds support for the bq24192i as I don't have a bq24192 to test with, adding support for the bq24192 should be as simple as also accepting its model-id in the model-id test.

2017-04-14power: reset: Add a driver for the Gemini poweroffLinus Walleij
The Gemini (SL3516) SoC has a special power controller block that only deal with shutting down the system. If you do not register a driver and activate the block, the power button on the systems utilizing this SoC will do an uncontrolled power cut, which is why it is important to have a special poweroff driver. The most basic functionality is to just shut down the system by writing a special bit in the control register after the system has reached pm_poweroff. It also handles the poweroff from a button or other sources: When the poweroff button is pressed, or a signal is sent to poweroff from an infrared remote control, or when the RTC fires a special alarm (!) the system emits an interrupt. At this point, Linux must acknowledge the interrupt and proceed to do an orderly shutdown of the system. After adding this driver, pressing the poweroff button gives this dmesg: root@gemini:/ root@gemini:/ gemini-poweroff 4b000000.power-controller: poweroff button pressed calling shutdown scripts.. setting /dev/rtc0 from system time unmounting file systems... umount: tmpfs busy - remounted read-only umount: can't unmount /: Invalid argument The system is going down NOW!

2017-04-14power: supply: max17040: Add OF device ID tableJavier Martinez Canillas
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2017-04-14power: bq24190_charger: Check the interrupt status on resumeTony Lindgren
Some SoCs like omap3 can configure GPIO irqs to use Linux generic dedicated wakeirq support. If the dedicated wakeirq is configured, the SoC will use a always-on interrupt controller to produce wake-up events. If bq24190 is configured for dedicated wakeirq, we need to check the interrupt status on PM runtime resume. This is because the Linux generic wakeirq will call pm_runtime_resume() on the device on a wakeirq. And as the bq24190 interrupt is falling edge sensitive and only active for 250 us, there will be no device interrupt seen by the runtime SoC IRQ controller. Note that this can cause spurious interrupts on omap3 devices with bq24190 connected to gpio banks 2 - 5 as there's a glitch on those pins waking from off mode as listed in "Advisory 1.45". Devices with this issue should not configure the optional wakeirq interrupt in the dts file.

2017-03-24IB/device: Convert ib-comp-wq to be CPU-boundSagi Grimberg
This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug.

2017-03-24infiniband: Fix alignment of mmap cookies to support VIPT cachingJason Gunthorpe
When vmalloc_user is used to create memory that is supposed to be mmap'd to user space, it is necessary for the mmap cookie (eg the offset) to be aligned to SHMLBA. This creates a situation where all virtual mappings of the same physical page share the same virtual cache index and guarantees VIPT coherence. Otherwise the cache is non-coherent and the kernel will not see writes by userspace when reading the shared page (or vice-versa).

2017-03-24i40iw: Receive netdev events post INET_NOTIFIER stateShiraz Saleem
Netdev notification events are de-registered only when all client iwdev instances are removed. If a single client is closed and re-opened, netdev events could arrive even before the Control Queue-Pair (CQP) is created, causing a NULL pointer dereference crash in i40iw_get_cqp_request. Fix this by allowing netdev event notification only after we have reached the INET_NOTIFIER state with respect to device initialization.

That code was acquired by mistake and has been a source of constant pain since then, so the time has come to get rid of it finally. We have not seen problems with this change in the lab, so fingers crossed. The rest is more usual: one more intel_pstate commit removing useless code, a cpufreq core fix to make it restore policy limits on CPU online (which prevents the limits from being reset over system suspend/resume), a schedutil cpufreq governor initialization fix to make it actually work as advertised on all systems and an extra sanity check in the cpuidle core to prevent crashes from happening if the arch code messes things up. Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Restore policy min/max limits on CPU online cpuidle: Validate cpu_dev in cpuidle_add_sysfs() cpufreq: intel_pstate: Fix policy data management in passive mode cpufreq: schedutil: Fix per-CPU structure initialization in sugov_start() cpufreq: intel_pstate: One set of global limits in active mode
