git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There are no too intrusive changes in this update batch. The biggest LOC is found in the new DICE driver, and other small changes are scattered over the whole sound subtree (which is a common pattern). Below are highlights: - ALSA core: * Memory allocation support with genpool * Fix blocking in drain ioctl of compress_offload - HD-audio: * Improved AMD HDMI supports * Intel HDMI detection improvements * thinkpad_acpi mute-key integration * New PCI ID, New ALC255,285,293 codecs, CX20952 - USB-audio: * New buffer size management * Clean up endpoint handling codes - ASoC: * Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers from drivers. * A refresh of the documentation. * Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. * Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it. - Firewire: DICE driver - Lots of small fixes for bugs reported by Coverity" * tag 'sound-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (382 commits) ALSA: hda/realtek - Add new codec ALC255/ALC3234 UAJ supported ALSA: hda - Apply MacBook fixups for CS4208 correctly ASoC: fsl: imx-wm8962: remove an unneeded check ASoC: fsl: imx-pcm-fiq: Remove unused 'runtime' variable ALSA: hda/realtek - Make fixup regs persist after resume ALSA: hda_intel: ratelimit "spurious response" message ASoC: generic-dmaengine-pcm: Use SNDRV_DMA_TYPE_DEV_IRAM as default ASoC: dapm: Use WARN_ON() instead of BUG_ON() ASoC: wm_adsp: Fix BUG_ON() and WARN_ON() usages ASoC: Replace BUG() with WARN() ASoC: wm_hubs: Replace BUG() with WARN() ASoC: wm8996: Replace BUG() with WARN() ASoC: wm8962: Replace BUG() with WARN() ASoC: wm8958: Replace BUG() with WARN() ASoC: wm8904: Replace BUG() with WARN() ASoC: wm8900: Replace BUG() with WARN() ASoC: wm8350: Replace BUG() with WARN() ASoC: txx9: Use WARN_ON() instead of BUG_ON() ASoC: sh: Use WARN_ON() instead of BUG_ON() ASoC: rcar: Use WARN_ON() instead of BUG_ON() ...

2013-10-22sony-laptop: don't change keyboard backlight settingsMattia Dongili1-17/+9
Do not touch keyboard backlight unless explicitly passed a module parameter. In this way we won't make wrong assumptions about what are good default values since they actually are different from model to model. The only side effect is that we won't know what is the current value until set via the sysfs attributes.

2013-10-18intel_mid: Renamed *mrst* to *intel_mid*Kuppuswamy Sathyanarayanan1-1/+1
mrst is used as common name to represent all intel_mid type soc's. But moorsetwon is just one of the intel_mid soc. So renamed them to use intel_mid. This patch mainly renames the variables and related functions that uses *mrst* prefix with *intel_mid*. To ensure that there are no functional changes, I have compared the objdump of related files before and after rename and found the only difference is symbol and name changes.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: 1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction of Intel Thunderbolt support on systems that use ACPI for signalling Thunderbolt hotplug events. This also should make ACPIPHP work in some cases in which it was known to have problems. From Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov. 2) ACPI core code cleanups and dock station support cleanups from Jiang Liu and Rafael J Wysocki. 3) Fixes for locking problems related to ACPI device hotplug from Rafael J Wysocki. 4) ACPICA update to version 20130725 includig fixes, cleanups, support for more than 256 GPEs per GPE block and a change to make the ACPI PM Timer optional (we've seen systems without the PM Timer in the field already). One of the fixes, related to the DeRefOf operator, is necessary to prevent some Windows 8 oriented AML from causing problems to happen. From Bob Moore, Lv Zheng, and Jung-uk Kim. 5) Removal of the old and long deprecated /proc/acpi/event interface and related driver changes from Thomas Renninger. 6) ACPI and Xen changes to make the reduced hardware sleep work with the latter from Ben Guthro. 7) ACPI video driver cleanups and a blacklist of systems that should not tell the BIOS that they are compatible with Windows 8 (or ACPI backlight and possibly other things will not work on them).

2013-08-23drivers/platform/olpc/olpc-ec.c: initialise earlierDaniel Drake1-1/+1
Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5a ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake <dsd@laptop.org> Cc: Andres Salomon <dilinger@queued.net> Cc: Paul Fox <pgf@laptop.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

It is quite some time that this one has been deprecated. Get rid of it. Should some really important user be overseen, it may be reverted and the userspace program worked on first, but it is time to do something to get rid of this old stuff...

2013-07-10Add trivial driver to disable Intel Smart ConnectMatthew Garrett3-0/+105
Intel Smart Connect is an Intel-specific ACPI interface for configuring devices to wake up at regular intervals so they can pull down mail or other internet updates, and then go to sleep again. If a user enables this in Windows and then reboots into Linux, the device may wake up if it's put to sleep. Since there's no Linux userland support for any of this, the machine will then remain awake until something else puts it back to sleep. I haven't figured out all that much about how this works (there's a bunch of different ACPI calls available on the device), but this seems to be enough to turn it off. We can add more features to this driver if anyone ever cares about figuring out what the rest of the calls do or writing some Linux userspace to implement the rest of it.

2013-07-10Add support driver for Intel Rapid Start TechnologyMatthew Garrett3-0/+222
Intel Rapid Start Technology is a firmware-based suspend-to-disk implementation. Once placed in S3, the device will wake once either a timeout elapses or the battery reaches a critical level. It will then resume to the firmware and copy the contents of RAM to a specialised partition, and then power off the machine. If the user turns the machine back on the firmware will copy the contents of the partition back to RAM and then resume from S3 as normal. This driver provides an interface for configuring the wakeup events and timeout. It still requires firmware support and an appropriate suspend partition.

Controlling the wlan led seems to have some side effects to the machines with wapf value is not equal to 4. It will make the keyboard backlight out of order. So, the patch will enable the wlan led function only if the wapf == 4.
