Merge tag 'sound-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "This became a fairly large pull request. In addition to the usual driver updates / fixes, there have been a high amount of cleanups in ASoC area, as well as control API helpers and kernel documentations fixes touching through the whole tree. In the driver side, the biggest changes are the support for new Intel SoC found on new x86 machines, and the updates of FireWire dice and oxfw drivers. Some remarkable items are below: ALSA core: - PCM mmap code cleanup, removal of arch-dependent codes - PCM xrun injection support - PCM hwptr tracepoint support - Refactoring of snd_pcm_action(), simplification of PCM locking - Robustified sequecner auto-load functionality - New control API helpers and lots of cleanups along with them - Lots of kerneldoc fixes and cleanups USB-audio: - The mixer resume code was largely rewritten, and the devices with quirks are resumed properly. - New hardware support: Focusrite Scarlett, Digidesign Mbox1, Denon/Marantz DACs, Zoom R16/24 FireWire: - DICE driver updates with better duplex and sync support, including MIDI support - New OXFW driver for Oxford Semiconductor FW970/971 chipset, including the previous LaCie Speakers device. Fullduplex and MIDI support included as well as DICE driver. HD-audio: - Refactoring the driver-caps quirk handling in snd-hda-intel - More consistent control names representing the topology better - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic fix, ASUS Z99He laptop EAPD ASoC: - Conversion of AC'97 drivers to use regmap, bringing us closer to the removal of the ASoC level I/O code - Clean up a lot of old drivers that were open coding things that have subsequently been implemented in the core - Some DAPM performance improvements - Removal of the now seldom used CODEC mutex - Lots of updates for the newer Intel SoC support, including support for the DSP and some Cherrytrail and Braswell machine drivers - Support for Samsung boards using rt5631 as the CODEC - Removal of the obsolete AFEB9260 machine driver - Driver support for the TI TS3A227E headset driver used in some Chrombeooks Others: - ASIHPI driver update and cleanups - Lots of dev_*() printk conversions - Lots of trivial cleanups for the codes spotted by Coccinelle" * tag 'sound-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (594 commits) ALSA: pcxhr: NULL dereference on probe failure ALSA: lola: NULL dereference on probe failure ALSA: hda - Add "eapd" model string for AD1986A codec ALSA: hda - Add EAPD fixup for ASUS Z99He laptop ALSA: oxfw: Add hwdep interface ALSA: oxfw: Add support for capture/playback MIDI messages ALSA: oxfw: add support for capturing PCM samples ALSA: oxfw: Add support AMDTP in-stream ALSA: oxfw: Add support for Behringer/Mackie devices ALSA: oxfw: Change the way to start stream ALSA: oxfw: Add proc interface for debugging purpose ALSA: oxfw: Change the way to make PCM rules/constraints ALSA: oxfw: Add support for AV/C stream format command to get/set supported stream formation ALSA: oxfw: Change the way to name card ALSA: dice: Add support for MIDI capture/playback ALSA: dice: Add support for capturing PCM samples ALSA: dice: Support for non SYT-Match sampling clock source mode ALSA: dice: Add support for duplex streams with synchronization ALSA: dice: Change the way to start stream ALSA: jack: Add dummy snd_jack_set_key() definition ...
