Pull sound updates from Takashi Iwai: "We've got many code additions at this cycle as a result of quite a few new drivers. Below are highlights: Core stuff: - Fix the long-standing issue with the device registration order; the control device is now registered at last - PCM locking code cleanups for RT kernels - Fixes for possible races in ALSA timer resolution accesses - TLV offset definitions in uapi ASoC: - Many fixes for the topology stuff, including fixes for v4 ABI compatibility - Lots of cleanups / quirks for Intel platforms based on Realtek CODECs - Continued componentization works, removing legacy CODEC stuff - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver - Fixes and updates to Cirrus Logic SoC drivers - New Qualcomm DSP support - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and RT5668 and TI TSCS454 HD-audio: - Finally better support for some CA0132 boards, allowing Windows firmware - HP Spectre x360 support along with a bulk of COEF stuff - Blacklisting power save default some known boards reported on Fedora USB-audio: - Continued improvements on UAC3 support; now BADD is supported - Fixes / improvements for Dell WD15 dock - Allow DMA coherent pages for PCM buffers for ARCH, MIPS & co Others: - New Xen sound frontend driver support - Cache implementation and other improvements for FireWire DICE - Conversions to octal permissions in allover places" * tag 'sound-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (386 commits) ASoC: dapm: delete dapm_kcontrol_data paths list before freeing it ALSA: usb-audio: remove redundant check on err ASoC: topology: Move skl-tplg-interface.h to uapi ASoC: topology: Move v4 manifest header data structures to uapi ASoC: topology: Improve backwards compatibility with v4 topology files ALSA: pci/hda: Remove unused, broken, header file ASoC: TSCS454: Add Support ASoC: Intel: kbl: Move codec sysclk config to codec_init function ASoC: simple-card: set cpu dai clk in hw_params ALSA: hda - Handle kzalloc() failure in snd_hda_attach_pcm_stream() ALSA: oxygen: use match_string() helper ASoC: dapm: use match_string() helper ASoC: max98095: use match_string() helper ASoC: max98088: use match_string() helper ASoC: Intel: bytcr_rt5651: Set card long_name based on quirks ASoC: mt6797-mt6351: add hostless phone call path ASoC: mt6797: add Hostless DAI ASoC: mt6797: add PCM interface ASoC: mediatek: export mtk-afe symbols as needed ASoC: codecs: PCM1789: include gpio/consumer.h ...

ALSA: usb-audio: UAC3 Add support for connector insertion.

2018-05-15T05:35:34+00:00

This adds support for the UAC3 insertion controls. The status is reported as a boolean value in the same way it used to do for UAC2. Hence, the presence of any connector in the response will make the control saying the jack is connected. The UAC2 support for this control has been moved to a dedicated control for connectors as both UAC2 and UAC3 follow a specific Control Request Parameter Block for this control. This parameter block for UAC3 could not be read in the same simplistic manner as in UAC2. This implementation is not requesting additional information from the HIGH CAPABILITY Connectors descriptor. Tested with an UAC3 device with UAC2 as legacy configuration. The connector status can be read with `amixer` and the interrupt is also caught with `alsactl monitor`.

usb: audio-v2: Correct the comment for struct uac_clock_selector_descriptor

2018-04-22T13:49:42+00:00

The comment in UAC2 clock selector descriptor definition mentions the bAssocTerminal after baCSourceID[], but it doesn't exist in the actual definition. Let's correct it.

ALSA: usb-audio: fix uac control query argument

2018-03-23T09:25:03+00:00

This patch fixes code readability and should have no functional change. Correct uac control query functions to account for the 1-based indexing of USB Audio Class control identifiers. The function parameter, u8 control, should be the constant defined in audio-v2.h to identify the control to be checked for readability or writeability. This patch fixes all callers that had adjusted, and makes explicit the mapping between audio_feature_info[] array index and the associated control identifier.

ALSA: usb: initial USB Audio Device Class 3.0 support

2018-03-21T10:46:33+00:00

Recently released USB Audio Class 3.0 specification introduces many significant changes comparing to previous versions, like - new Power Domains, support for LPM/L1 - new Cluster descriptor - changed layout of all class-specific descriptors - new High Capability descriptors - New class-specific String descriptors - new and removed units - additional sources for interrupts - removed Type II Audio Data Formats - ... and many other things (check spec) It also provides backward compatibility through multiple configurations, as well as requires mandatory support for BADD (Basic Audio Device Definition) on each ADC3.0 compliant device This patch adds initial support of UAC3 specification that is enough for Generic I/O Profile (BAOF, BAIF) device support from BADD document.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.
