Merge tag 'sound-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "As the diffstat shows we've had again a lot of works done for this cycle: the majority of changes are the continued componentization and code refactoring in ASoC, the tree-wide PCM API updates and cleanups and SOF updates while a few ASoC driver updates are seen, too. Here we go, some highlights: Core: - Finally y2038 support landed to ALSA ABI; some ioctls have been extended and lots of tricks were applied - Applying the new managed PCM buffer API to all drivers; the API itself was already merged in 5.5 - The already deprecated dimension support in ALSA control API is dropped completely now - Verification of ALSA control elements to catch API misuses ASoC: - Further code refactorings and moving things to the component level - Lots of updates and improvements on SOF / Intel drivers; now including common HDMI driver and SoundWire support - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015 and RT1308 HD-audio: - Improved ring-buffer communications using waitqueue - Drop the superfluous buffer preallocation on x86 Others: - Many code cleanups, mostly constifications over the whole tree - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix - FireWire: code refactoring for oxfw and dice drivers" * tag 'sound-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (638 commits) ALSA: usb-audio: add quirks for Line6 Helix devices fw>=2.82 ALSA: hda: Add Clevo W65_67SB the power_save blacklist ASoC: soc-core: remove null_snd_soc_ops ASoC: soc-pcm: add soc_rtd_trigger() ASoC: soc-pcm: add soc_rtd_hw_free() ASoC: soc-pcm: add soc_rtd_hw_params() ASoC: soc-pcm: add soc_rtd_prepare() ASoC: soc-pcm: add soc_rtd_shutdown() ASoC: soc-pcm: add soc_rtd_startup() ASoC: rt1015: add rt1015 amplifier driver ASoC: madera: Correct some kernel doc ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization order ASoC: Intel: skl_hda_dsp_common: Fix global-out-of-bounds bug ASoC: madera: Correct DMIC only input hook ups ALSA: cs46xx: fix spelling mistake "to" -> "too" ALSA: hda - Add docking station support for Lenovo Thinkpad T420s ASoC: Add MediaTek MT6660 Speaker Amp Driver ASoC: dt-bindings: rt5645: add suppliers ASoC: max98090: fix deadlock in max98090_dapm_put_enum_double() ASoC: dapm: add snd_soc_dapm_put_enum_double_locked ...
