libnvdimm-for-4.4
ab27a8d0 · ·libnvdimm for 4.4: 1/ Add support for the ACPI 6.0 NFIT hot add mechanism to process updates of the NFIT at runtime. 2/ Teach the coredump implementation how to filter out DAX mappings. 3/ Introduce NUMA hints for allocations made by the pmem driver, and as a side effect all devm allocations now hint their NUMA node by default.

pm+acpi-4.4-rc1-1
1ab68460 · ·Power management and ACPI updates for v4.4-rc1 - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar). This should help to simplify the CPU offline/online handling among other things. - cpufreq core fixes and cleanups (Viresh Kumar). - intel_pstate fixes related to the Turbo Activation Ratio (TAR) mechanism on client platforms which causes the turbo P-states range to vary depending on platform firmware settings (Srinivas Pandruvada). - intel_pstate sysfs interface fix (Prarit Bhargava). - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G Bhat, Luis de Bethencourt). - cpuidle mvebu driver cleanups (Russell King). - OPP (Operating Performance Points) framework code reorganization to make it more maintainable (Viresh Kumar). - Intel Broxton support for the RAPL (Running Average Power Limits) power capping driver (Amy Wiles). - Assorted power management code fixes and cleanups (Dan Carpenter, Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus Villemoes). /

gpio-v4.4-1
0963670a · ·This is the bulk of GPIO changes for v4.4: GPIO core: - Define and handle flags for open drain/open collector and open source/open emitter, also know as "single-ended" configurations. - Generic request/free operations that handle calling out to the (optional) pin control backend. - Some refactoring related to an ABI change that did not happen, yet provide useful. - Added a real-time compliance checklist. Many GPIO chips have irqchips, and need to think this over with the RT patches going upstream. - Restructure, fix and clean up Kconfig menus a bit. New drivers: - New driver for AMD Promony. - New driver for ACCES 104-IDIO-16, a port-mapped I/O card, ISA-style. Very retro. Subdriver changes: - OMAP changes to handle real time requirements. - Handle trigger types for edge and level IRQs on PL061 properly. As this hardware is very common it needs to set a proper example for others to follow. - Some container_of() cleanups. - Delete the unused MSM driver in favor of the driver that is embedded inside the pin control driver. - Cleanup of the ath79 GPIO driver used by many, many OpenWRT router targets. - A consolidated IT87xx driver replacing the earlier very specific IT8761e driver. - Handle the TI TCA9539 in the PCA953x driver. Also handle ACPI devices in this subdriver. - Drop xilinx arch dependencies as these FPGAs seem to profilate over a few different architectures. MIPS and ARM come to mind.
