git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "The majority of this update is about ASoC, including a few new drivers, and the rest are mostly minor changes. The only substantial change in ALSA core is about the additional error handling in the compress-offload API. Below are highlights: - Add the error propagating support in compress-offload API - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the default mixer setup change ot turn off the loopback - Lots of updates for ASoC Intel drivers, mostly board support and bug fixing, and to the NAU8825 driver - Work on generalizing bits of simple-card to allow more code sharing with the Renesas rsrc-card (which can't use simple-card due to DPCM) - Removal of the Odroid X2 driver due to replacement with simple-card - Support for several new Mediatek platforms and associated boards - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504, Realtek RT5514 and Wolfson WM8758" * tag 'sound-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (278 commits) sound: oss: Use kernel_read_file_from_path() for mod_firmware_load() ASoC: Intel: Skylake: Delete an unnecessary check before the function call "release_firmware" ASoC: Intel: Skylake: Fix NULL Pointer exception in dynamic_debug.

2016-07-22ACPI / processor_idle: Add support for Low Power Idle(LPI) statesSudeep Holla1-3/+21
ACPI 6.0 introduced an optional object _LPI that provides an alternate method to describe Low Power Idle states. It defines the local power states for each node in a hierarchical processor topology. The OSPM can use _LPI object to select a local power state for each level of processor hierarchy in the system. They used to produce a composite power state request that is presented to the platform by the OSPM. Since multiple processors affect the idle state for any non-leaf hierarchy node, coordination of idle state requests between the processors is required. ACPI supports two different coordination schemes: Platform coordinated and OS initiated. This patch adds initial support for Platform coordination scheme of LPI.

ACPI 6.0 adds a new method to specify the CPU idle states(C-states) called Low Power Idle(LPI) states. Since new architectures like ARM64 use only LPIs, introduce ACPI_PROCESSOR_CSTATE to encapsulate all the code supporting the old style C-states(_CST). This patch will help to extend the processor_idle module to support LPI. Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

2016-06-26device property: Add function to search for named child of deviceAdam Thomson1-0/+7
For device nodes in both DT and ACPI, it possible to have named child nodes which contain properties (an existing example being gpio-leds). This adds a function to find a named child node for a device which can be used by drivers for property retrieval. For DT data node name matching, of_node_cmp() and similar functions are made available outside of CONFIG_OF block so the new function can reference these for DT and non-DT builds. For ACPI data node name matching, a helper function is also added which returns false if CONFIG_ACPI is not set, otherwise it performs a string comparison on the data node name. This avoids using the acpi_data_node struct for non CONFIG_ACPI builds, which would otherwise cause a build failure.

2016-05-30ACPI / processor: Add acpi_map_madt_entry()David Daney1-0/+1
Follow-on arm64 ACPI/NUMA patches need to map MADT entries very early (before kmalloc is usable). Add acpi_map_madt_entry() which, indirectly, uses early_memremap()/early_memunmap() to access the table and parse out the mpidr. The existing implementation of map_madt_entry() is modified to take a pointer to the MADT as a parameter and the callers adjusted.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this update was stabilized before the merge window and appeared in -next. The "device dax" implementation was revised this week in response to review feedback, and to address failures detected by the recently expanded ndctl unit test suite. Not included in this pull request are two dax topic branches (dax error handling, and dax radix-tree locking). These topics were deferred to get a few more days of -next integration testing, and to coordinate a branch baseline with Ted and the ext4 tree. Vishal and Ross will send the error handling and locking topics respectively in the next few days. This branch has received a positive build result from the kbuild robot across 226 configs. Summary: - Device DAX for persistent memory: Device DAX is the device-centric analogue of Filesystem DAX (CONFIG_FS_DAX). It allows memory ranges to be allocated and mapped without need of an intervening file system. Device DAX is strict, precise and predictable. Specifically this interface: a) Guarantees fault granularity with respect to a given page size (pte, pmd, or pud) set at configuration time. b) Enforces deterministic behavior by being strict about what fault scenarios are supported. Persistent memory is the first target, but the mechanism is also targeted for exclusive allocations of performance/feature differentiated memory ranges. - Support for the HPE DSM (device specific method) command formats. This enables management of these first generation devices until a unified DSM specification materializes. - Further ACPI 6.1 compliance with support for the common dimm identifier format. - Various fixes and cleanups across the subsystem" * tag 'libnvdimm-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (40 commits) libnvdimm, dax: fix deletion libnvdimm, dax: fix alignment validation libnvdimm, dax: autodetect support libnvdimm: release ida resources Revert "block: enable dax for raw block devices" /dev/dax, core: file operations and dax-mmap /dev/dax, pmem: direct access to persistent memory libnvdimm: stop requiring a driver ->remove() method libnvdimm, dax: record the specified alignment of a dax-device instance libnvdimm, dax: reserve space to store labels for device-dax libnvdimm, dax: introduce device-dax infrastructure nfit: add sysfs dimm 'family' and 'dsm_mask' attributes tools/testing/nvdimm: ND_CMD_CALL support nfit: disable vendor specific commands nfit: export subsystem ids as attributes nfit: fix format interface code byte order per ACPI6.1 nfit, libnvdimm: limited/whitelisted dimm command marshaling mechanism nfit, libnvdimm: clarify "commands" vs "_DSMs" libnvdimm: increase max envelope size for ioctl acpi/nfit: Add sysfs "id" for NVDIMM ID ...

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

The ACPI specification states that arguments "Revision ID" and "Function Index" to a _DSM are type "Integer." Type Integers are 64 bit quantities. The function evaluate_dsm specifies these types as simple "int" which are 32 bits. Widen type passed to acpi_evaluate_dsm and its callers and derived callers to pass correct type. acpi_check_dsm and acpi_evaluate_dsm_typed had similar issue and were corrected as well.

2016-04-09ACPI / utils: Rename acpi_dev_present()Lukas Wunner1-1/+1
acpi_dev_present() was originally named after pci_dev_present() to signify the similarity of the two functions. However Rafael J. Wysocki pointed out that the exported function acpi_dev_present() is easily confused with the non-exported acpi_device_is_present(). Additionally in ACPI parlance the term "present" usually refers to the "device is present" bit returned by the _STA control method, yet acpi_dev_present() merely checks presence in the namespace. It does not invoke _STA at all, let alone check the "device is present" bit. As suggested by Rafael, rename the function to acpi_dev_found() and adjust all existing call sites.
