git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There have been lots of changes in ALSA core, HD-audio and ASoC, also most of PCI drivers touched by conversions of printks. All these resulted in a high volume and wide ranged patch sets in this release. Many changes are fairly trivial, but also lots of nice cleanups and refactors. There are a few new drivers, most notably, the Intel Haswell and Baytrail ASoC driver. Core changes: - A bit modernization; embed the device struct into snd_card struct, so that it may be referred from the beginning. A new snd_card_new() function is introduced for that, and all drivers have been converted. - Simplification in the device management code in ALSA core; now managed by a simple priority list instead - Converted many kernel messages to use the standard dev_err() & co; this would be the pretty visible difference, especially for HD-audio. HD-audio: - Conexant codecs use the auto-parser as default now; the old static code still remains in case of regressions. Some old quirks have been rewritten with the fixups for auto-parser. - C-Media codecs also use the auto-parser as default now, too. - A device struct is assigned to each HD-audio codec, and the formerly hwdep attributes are accessible over the codec sysfs, too. hwdep attributes still remain for compatibility. - Split the PCI-specific stuff for HD-audio controller into a separate module, ane make a helper module for the generic controller driver. This is a preliminary change for supporting Tegra HDMI controller in near future, which slipped from 3.15 merge. - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more Dell laptop headset quirks - Make the HD-audio codec response a bit more robust - A few improvements on Realtek ALC282 / 283 about the pop noises - A couple of Intel HDMI fixes ASoC: - Lots of cleanups for enumerations; refactored lots of error prone original codes to use more modern APIs - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues - DPCM support for Intel Haswell and Bay Trail platforms, lots of fixes - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8 - Fixes for the simple-card DAI format DT mess - DT support for a couple more devices. - Use of the tdm_slot mapping in a few drivers Others: - Support of reset_resume callback for improved S4 in USB-audio driver; the device with boot quirks have been little tested, which we need to watch out in this development cycle - Add PM support for ICE1712 driver (finally!); it's still pretty partial support, only for M-Audio devices" * tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (610 commits) ALSA: ice1712: Add suspend support for M-Audio ICE1712-based cards ALSA: ice1712: add suspend support for ICE1712 chip ALSA: hda - Enable beep for ASUS 1015E ALSA: asihpi: fix some indenting in snd_card_asihpi_pcm_new() ALSA: hda - add headset mic detect quirks for three Dell laptops ASoC: tegra: move AC97 clock handling to the machine driver ASoC: simple-card: Handle many DAI links ASoC: simple-card: Add DT documentation for multi-DAI links ASoC: simple-card: dynamically allocate the DAI link and properties ASoC: imx-ssi: Add .xlate_tdm_slot_mask() support.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "As far as the number of commits goes, the top spot belongs to ACPI this time with cpufreq in the second position and a handful of PM core, PNP and cpuidle updates. They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper. From Jiang Liu. - New Win8 OSI blacklist entries from Takashi Iwai. - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria, Tang Chen, Zhang Rui. - intel_pstate driver updates, including proper Baytrail support, from Dirk Brandewie and intel_pstate documentation from Ramkumar Ramachandra. - Generic CPU boost ("turbo") support for cpufreq from Lukasz Majewski. - powernow-k6 cpufreq driver fixes from Mikulas Patocka. - cpufreq core fixes and cleanups from Viresh Kumar, Jane Li, Mark Brown. - Assorted cpufreq drivers fixes and cleanups from Anson Huang, John Tobias, Paul Bolle, Paul Walmsley, Sachin Kamat, Shawn Guo, Viresh Kumar. - cpuidle cleanups from Bartlomiej Zolnierkiewicz. - Support for hibernation APM events from Bin Shi. - Hibernation fix to avoid bringing up nonboot CPUs with ACPI EC disabled during thaw transitions from Bjørn Mork. - PM core fixes and cleanups from Ben Dooks, Leonardo Potenza, Ulf Hansson. - PNP subsystem fixes and cleanups from Dmitry Torokhov, Levente Kurusa, Rashika Kheria. - New tool for profiling system suspend from Todd E Brandt and a cpupower tool cleanup from One Thousand Gnomes" * tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (153 commits) thermal: exynos: boost: Automatic enable/disable of BOOST feature (at Exynos4412) cpufreq: exynos4x12: Change L0 driver data to CPUFREQ_BOOST_FREQ Documentation: cpufreq / boost: Update BOOST documentation cpufreq: exynos: Extend Exynos cpufreq driver to support boost cpufreq / boost: Kconfig: Support for software-managed BOOST acpi-cpufreq: Adjust the code to use the common boost attribute cpufreq: Add boost frequency support in core intel_pstate: Add trace point to report internal state. cpufreq: introduce cpufreq_generic_get() routine ARM: SA1100: Create dummy clk_get_rate() to avoid build failures cpufreq: stats: create sysfs entries when cpufreq_stats is a module cpufreq: stats: free table and remove sysfs entry in a single routine cpufreq: stats: remove hotplug notifiers cpufreq: stats: handle cpufreq_unregister_driver() and suspend/resume properly cpufreq: speedstep: remove unused speedstep_get_state platform: introduce OF style 'modalias' support for platform bus PM / tools: new tool for suspend/resume performance optimization ACPI: fix module autoloading for ACPI enumerated devices ACPI: add module autoloading support for ACPI enumerated devices ACPI: fix create_modalias() return value handling ...

2014-01-21fujitsu-laptop: fix error return codeJulia Lawall1-8/+7
These functions mix the use of result and error. In acpi_fujitsu_add, result does not seem useful; it would seem reasonable to propagate the return value of acpi_bus_update_power in an error case. On the other hand, in the case of acpi_fujitsu_hotkey_add, there is an initialization of result that can lead to what looks like a failure case, but that does not abort the function. The variable result is kept for this case. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2014-01-21dell-laptop: Only install the i8042 filter when rfkill is activeHans de Goede1-31/+32
Installing the i8042 filter is not useful on machines where rfkill is not whitelisted, so move the filter installation into dell_setup_rfkill, after the whitelist check. This avoids doing a needless and potentially troublesome rfkill query (dell_send_request(buf, 17, 11)) when the wireless Fn key gets pressed on non whitelisted laptops. This patch was written as a result of: https://bugzilla.redhat.com/show_bug.cgi?id=1045807 It is not yet clear if this is related, but it is a good idea to not register the i8042 filter in general.

2014-01-21X86 platform: New BayTrail IOSF-SB MBI driverDavid E. Box4-0/+323
Current Intel SOC cores use a MailBox Interface (MBI) to provide access to unit devices connected to the system fabric. This driver implements access to this interface on BayTrail platforms. This is a requirement for drivers that need access to unit registers on the platform (e.g. accessing the PUNIT for power management features such as RAPL). Serialized access is handled by all exported routines with spinlocks. The API includes 3 functions for access to unit registers: int bt_mbi_read(u8 port, u8 opcode, u32 offset, u32 *mdr) int bt_mbi_write(u8 port, u8 opcode, u32 offset, u32 mdr) int bt_mbi_modify(u8 port, u8 opcode, u32 offset, u32 mdr, u32 mask) port: indicating the unit being accessed opcode: the read or write port specific opcode offset: the register offset within the port mdr: the register data to be read, written, or modified mask: bit locations in mdr to change Returns nonzero on error Note: GPU code handles access to the GFX unit. Therefore access to that unit with this driver is disallowed to avoid conflicts. Signed-off-by: David E. Box <david.e.box@linux.intel.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng25-58/+23
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

2013-11-26sony-laptop: do not scribble keyboard backlight registers on resumeMattia Dongili1-27/+0
Follow-up to commit 294d31e8227c ("sony-laptop: don't change keyboard backlight settings"): avoid messing up the state on resume. Leave it to what was before suspending as it's anyway likely that we still don't know what value we should write to the EC registers.

2013-11-25platform/chrome: chromeos_laptop - Use deferred probingBenson Leung1-43/+101
Further refactor chromeos_laptop, adding a probe function. Init will call dmi_check_system, but will only use the match to select a chromeos_laptop structure of the current board. Probe will add the devices, and on errors return -EPROBE_DEFER. If i2c adapters are loaded after chromeos_laptop inits, the deferred probe will instantiate the peripherals when the bus appears.

2013-11-25platform/chrome: chromeos_laptop - Restructure device associationsAaron Durbin1-71/+126
The previous code had a single DMI matching entry for each device on a board. Instead provide a single DMI entry for each board which references a structure about each board that lists the associated peripherals. This allows for a lower number of DMI matching sequences as well making it easier to add new boards.

2013-11-20ipc: Added support for IPC interrupt modeKuppuswamy Sathyanarayanan1-3/+45
This patch adds support for ipc command interrupt mode. Also added platform data option to select 'irq_mode' irq_mode = 1: configure the driver to receive IOC interrupt for each successful ipc_command. irq_mode = 0: makes driver use polling method to track the command completion status.

2013-11-20ipc: Added platform data structureKuppuswamy Sathyanarayanan1-8/+29
Since the same ipc driver can be used by many platforms, using macros for defining ipc_base and i2c_base addresses is not a scalable approach.

2013-11-20platform: add chrome platform directoryOlof Johansson7-12/+32
It makes sense to split out the Chromebook/Chromebox hardware platform drivers to a separate subdirectory, since some of it will be shared between ARM and x86. This moves over the existing chromeos_laptop driver without making any other changes, and adds appropriate Kconfig entries for the new directory. It also adds a MAINTAINERS entry for the new subdir.

2013-11-20sony-laptop: warn on multiple KBD backlight handlesMattia Dongili1-4/+12
Some BIOS versions/Vaio models apparently ship with two nearly identical functions to handle backlight related controls. The only difference seems to be: If (LEqual (BUF1, 0x40)) { Store (0x40, P80H) Store (BUF2, Local0) - And (Local0, One, Local0) + And (Local0, 0x03, Local0) Store (Local0, ^^H_EC.KLPC) } Avoid erroring out on initialization and messing things up on cleanup for now since we never call into these methods with anything different than 1 or 0.
