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() ...

| * mfd: intel-lpss: Pass SDA hold time to I2C host controller driverMika Westerberg2015-12-072-10/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel Skylake the LPSS I2C pad circuit has internal delays that require programming non-zero SDA hold time for the I2C host controller. If this is not done communication to slave devices may fail with arbitration lost errors like the one seen below taken from Lenovo Yoga 900: i2c_hid i2c-SYNA2B29:00: Fetching the HID descriptor i2c_hid i2c-SYNA2B29:00: __i2c_hid_command: cmd=20 00 i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration To fix this we follow what the Windows driver is doing and pass the default SDA hold time of 230 ns to all Intel Skylake host controllers. This still allows the platform to override these values by passing special ACPI methods SSCN and FMCN.

| * mfd: intel-lpss: Add support for passing device propertiesMika Westerberg2015-12-072-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the boot firmware does not support ACPI we need a way to pass device configuration information to the drivers. The unified device properties API already supports passing platform data via properties so let's take advantage of that and allow probe drivers to pass set of properties to the host controller driver. In order to do that we need to be able to modify the MFD cell corresponding the host controller, so make the core driver to take copy of the cell instead of using it directly. Then we can assign info->pset to the resulting copy of a cell and let the MFD core to assign that to the resulting device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 54e8827d5f0e ("mfd: sec-core: Add support for S2MPU02 device") added new MFD child devices for S2MPU02: RTC and clock provider (the clock provider with new compatible). However support for these devices was not added to existing drivers (rtc-s5m, clk-s2mps11). New drivers were not submitted neither. This means that the name of children devices is completely unused. The "samsung,s2mpu02-clk" compatible remains undocumented so it is unclear what is provided by that compatible. Clean up this by removing unused child devices and undocumented compatible.

However on some boards (with S2MPS13) the pin is pulled down so any suspend will effectively trigger the reset of bucks supplying the power to the little and big cores. In the same time when resuming, these bucks must provide voltage greater or equal to voltage before suspend to match the frequency chosen by cpufreq. If voltage (default value of voltage after reset) is lower than one set by cpufreq before suspend, then system will hang during resuming.

The Flexcom is a wrapper which integrates one SPI controller, one I2C controller and one USART. Only one function can be enabled at a time. This driver selects the function once for all, when the Flexcom is probed, according to the value of the new "atmel,flexcom-mode" device tree property. This driver has chosen to present the Flexcom to the system as a MFD so the implementation is seamless for the existing Atmel SPI, I2C and USART drivers. Also the Flexcom embeds FIFOs: the latest patches of the SPI, I2C and USART drivers take advantage of this new feature.
