Merge tag 'sound-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "The majority of changes are ASoC drivers (SOF, Intel, AMD, Mediatek, Qualcomm, TI, Apple Silicon, etc), while we see a few small fixes in ALSA / ASoC core side, too. Here are highlights: Core: - A new string helper parse_int_array_user() and cleanups with it - Continued cleanup of memory allocation helpers - PCM core optimization and hardening - Continued ASoC core code cleanups ASoC: - Improvements to the SOF IPC4 code, especially around trace - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silicon systems, Everest ES8326, Intel Sky Lake and Kaby Lake, Mediatek MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450 and Texas Instruments SRC4392 HD- and USB-audio: - Cleanups for unification of hda-ext bus - HD-audio HDMI codec driver cleanups - Continued endpoint management fixes for USB-audio - New quirks as usual" * tag 'sound-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (422 commits) ALSA: hda: Fix position reporting on Poulsbo ALSA: hda/hdmi: Don't skip notification handling during PM operation ASoC: rockchip: i2s: use regmap_read_poll_timeout_atomic to poll I2S_CLR ASoC: dt-bindings: Document audio OF graph dai-tdm-slot-num dai-tdm-slot-width props ASoC: qcom: fix unmet direct dependencies for SND_SOC_QDSP6 ALSA: usb-audio: Fix potential memory leaks ALSA: usb-audio: Fix NULL dererence at error path ASoC: mediatek: mt8192-mt6359: Set the driver name for the card ALSA: hda/realtek: More robust component matching for CS35L41 ASoC: Intel: sof_rt5682: remove SOF_RT1015_SPEAKER_AMP_100FS flag ASoC: nau8825: Add TDM support ASoC: core: clarify the driver name initialization ASoC: mt6660: Fix PM disable depth imbalance in mt6660_i2c_probe ASoC: wm5102: Fix PM disable depth imbalance in wm5102_probe ASoC: wm5110: Fix PM disable depth imbalance in wm5110_probe ASoC: wm8997: Fix PM disable depth imbalance in wm8997_probe ASoC: wcd-mbhc-v2: Revert "ASoC: wcd-mbhc-v2: use pm_runtime_resume_and_get()" ASoC: mediatek: mt8186: Fix spelling mistake "slect" -> "select" ALSA: hda/realtek: Add quirk for HP Zbook Firefly 14 G9 model ALSA: asihpi - Remove unused struct hpi_subsys_response ...
