2016-03-21Merge tag 'arm64-perf' of ↵Linus Torvalds2-0/+13
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm[64] perf updates from Will Deacon: "I have another mixed bag of ARM-related perf patches here. It's about 25% CPU and 75% interconnect, but with drivers/bus/ languishing without an obvious maintainer or tree, Olof and I agreed to keep all of these PMU patches together. I suspect a whole load of code from drivers/bus/arm-* can be moved under drivers/perf/, so that's on the radar for the future. Summary: - Initial support for ARMv8.1 CPU PMUs - Support for the CPU PMU in Cavium ThunderX - CPU PMU support for systems running 32-bit Linux in secure mode - Support for the system PMU in ARM CCI-550 (Cache Coherent Interconnect)" * tag 'arm64-perf' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (26 commits) drivers/perf: arm_pmu: avoid NULL dereference when not using devicetree arm64: perf: Extend ARMV8_EVTYPE_MASK to include PMCR.LC arm-cci: remove unused variable arm-cci: don't return value from void function arm-cci: make private functions static arm-cci: CoreLink CCI-550 PMU driver arm-cci500: Rearrange PMU driver for code sharing with CCI-550 PMU arm-cci: CCI-500: Work around PMU counter writes arm-cci: Provide hook for writing to PMU counters arm-cci: Add helper to enable PMU without synchornising counters arm-cci: Add routines to save/restore all counters arm-cci: Get the status of a counter arm-cci: write_counter: Remove redundant check arm-cci: Delay PMU counter writes to pmu::pmu_enable arm-cci: Refactor CCI PMU enable/disable methods arm-cci: Group writes to counter arm-cci: fix handling cpumask_any_but return value arm-cci: simplify sysfs attr handling drivers/perf: arm_pmu: implement CPU_PM notifier arm64: dts: Add Cavium ThunderX specific PMU ...

2016-02-26arm64: dts: marvell: add Device Tree files for Armada 7K/8KThomas Petazzoni1-0/+24
This commit adds the base Device Tree files for the Armada 7K and 8K SoCs, as well as the Armada 8040 DB board. The Armada 7020, 7040 (7K family) and 8020, 8040 (8K family) are composed of: - An AP806 block that contains the CPU core and a few basic peripherals. The AP806 is available in dual core configurations (used in 7020 and 8020) and quad core configurations (used in 8020 and 8040). - One or two CP110 blocks that contain all the high-speed interfaces (SATA, PCIe, Ethernet, etc.). The 7K family chips have one CP110, and the 8K family chips have two CP110, giving them twice the number of HW interfaces. In order to represent this from a Device Tree point of view, this commit creates the following hierarchy: * armada-ap806.dtsi - definitions common to dual/quad ap806 * armada-ap806-dual.dtsi - description of the two CPUs * armada-7020.dtsi - description of the 7020 SoC * armada-8020.dtsi - description of the 8020 SoC * armada-ap806-quad.dtsi - description of the four CPUs * armada-7040.dtsi - description of the 7040 SoC * armada-7040-db.dts - description of the 7040 board * armada-8040.dtsi - description of the 8040 SoC The CP110 blocks are not described yet, and will be part of future patch series.

2016-02-24devicetree: bindings: Document qcom board compatible formatStephen Boyd1-0/+51
Some qcom based bootloaders identify the dtb blob based on a set of device properties like SoC, platform, PMIC, and revisions of those components. In downstream kernels, these values are added to the different component dtsi files (i.e. pmic dtsi file, SoC dtsi file, board dtsi file, etc.) via qcom specific DT properties. The dtb files are parsed by a program called dtbTool that picks out these properties and creates a table of contents binary blob with the property information and some offsets into the concatenation of all the dtbs (termed a QCDT image). The suggestion is to do this via the board compatible string instead, because these qcom specific properties are never used by the kernel. Add a document describing the format of the compatible string that encodes all this information that's currently encoded in the qcom,{msm-id,board-id,pmic-id} properties in downstream devicetrees. Future bootloaders may be updated to look at the compatible field instead of looking for the table of contents image. For non-updateable bootloaders, a new dtbTool program will parse the compatible string and generate a QCDT image from it.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull oower management and ACPI updates from Rafael Wysocki: "As far as the number of commits goes, ACPICA takes the lead this time, followed by cpufreq and the device properties framework changes. The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over. Specifics: - Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki). In particular, the previously added erroneous support for the _SUB object is dropped, the concatenate operator will support all ACPI objects now, the Debug Object handling is improved, the SuperName handling of parameters being control methods is fixed, the ObjectType operator handling is updated to follow ACPI 5.0A and the handling of CondRefOf and RefOf is updated accordingly, module- level code will be executed after loading each ACPI table now (instead of being run once after all tables containing AML have been loaded), the Operation Region handlers management is updated to fix some reported problems and a the ACPICA code in the kernel is more in line with the upstream now. - Update the ACPI backlight driver to provide information on whether or not it will generate key-presses for brightness change hotkeys and update some platform drivers (dell-wmi, thinkpad_acpi) to use that information to avoid sending double key-events to users pace for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht). - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard). - Fix the handling of the list of device IDs of device objects found in the ACPI namespace and add a helper for checking if there is a device object for a given device ID (Lukas Wunner). - Change the logic in the ACPI namespace scanning code to create struct acpi_device objects for all ACPI device objects found in the namespace even if _STA fails for them which helps to avoid device enumeration problems on Microsoft Surface 3 (Aaron Lu). - Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). - Assorted updates of the PM core and related code (Julia Lawall, Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf Hansson). - PNP bus type updates (Christophe Le Roy, Heiner Kallweit). - PCI PM code cleanups (Jarkko Nikula, Julia Lawall). - cpupower tool updates (Jacob Tanenbaum, Thomas Renninger)" * tag 'pm+acpi-4.5-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (177 commits) PM / clk: don't leave clocks enabled when driver not bound i2c: dw: Add APM X-Gene ACPI I2C device support ACPI / APD: Add APM X-Gene ACPI I2C device support ACPI / LPSS: change 'does not have' to 'has' in comment Revert "dmaengine: dw: platform: provide platform data for Intel" dmaengine: dw: return immediately from IRQ when DMA isn't in use dmaengine: dw: platform: power on device on shutdown ACPI / LPSS: override power state for LPSS DMA device PM / OPP: Use snprintf() instead of sprintf() Documentation: cpufreq: intel_pstate: enhance documentation ACPI, PCI, irq: remove redundant check for null string pointer ACPI / video: driver must be registered before checking for keypresses cpufreq-dt: fix handling regulator_get_voltage() result cpufreq: governor: Fix negative idle_time when configured with CONFIG_HZ_PERIODIC PM / sleep: Add support for read-only sysfs attributes ACPI: Fix white space in a structure definition ACPI / SBS: fix inconsistent indenting inside if statement PNP: respect PNP_DRIVER_RES_DO_NOT_CHANGE when detaching ACPI / PNP: constify device IDs ACPI / PCI: Simplify acpi_penalize_isa_irq() ...
