Merge tag 'sound-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Not much dramatic changes at this time, but we've received quite a lot of changes for ASoC, while there are still a few fixes and quirks for usual HD- and USB-auido. Here are some highlights. ASoC: - Overhaul of endianness specification for data formats, avoiding needless restrictions due to CODECs - Initial stages of Intel AVS driver merge - Introduction of v4 IPC mechanism for SOF - TDM mode support for AK4613 - Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces, nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780 Others: - A few regression fixes after the USB-audio endpoint management refactoring - More enhancements for Cirrus HD-audio codec support (still ongoing) - Addition of generic serial MIDI driver" * tag 'sound-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (504 commits) ALSA: hda/realtek - Add new type for ALC245 ALSA: usb-audio: Configure sync endpoints before data ALSA: ctxfi: fix typo in comment ALSA: cs5535audio: fix typo in comment ALSA: ctxfi: Add SB046x PCI ID ALSA: usb-audio: Add missing ep_idx in fixed EP quirks ALSA: usb-audio: Workaround for clock setup on TEAC devices ALSA: lola: Bounds check loop iterator against streams array size ASoC: max98090: Move check for invalid values before casting in max98090_put_enab_tlv() ASoC: rt1308-sdw: add the default value of register 0xc320 ASoC: rt9120: Use pm_runtime and regcache to optimize 'pwdnn' logic ASoC: rt9120: Fix 3byte read, valule offset typo ASoC: amd: acp: Set Speaker enable/disable pin through rt1019 codec driver.
