Merge tag 'sound-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
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 ...
