Merge tag 'sound-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "The major changes in the core API side in this cycle are the still on-going ASoC componentization works. Other than that, only few small changes such as 20bit PCM format support are found. Meanwhile the rest majority of changes are for ASoC drivers: - Large cleanups of some of the TI CODEC drivers - Continued work on Intel ASoC stuff for new quirks, ACPI GPIO handling, Kconfigs and lots of cleanups - Refactoring of the Freescale SSI driver, as preliminary work for the upcoming changes - Work on ST DFSDM driver, including the required IIO patches - New drivers for Allwinner A83T, Maxim MAX89373, SocioNext UiniPhier EVEA Tempo Semiconductor TSCS42xx and TI PCM816x, TAS5722 and TAS6424 devices - Removal of dead codes for SN95031 and board drivers Last but not least, a few HD-audio and USB-audio quirks are included as usual, too" * tag 'sound-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (303 commits) ALSA: hda - Reduce the suspend time consumption for ALC256 ASoC: use seq_file to dump the contents of dai_list,platform_list and codec_list ASoC: soc-core: add missing EXPORT_SYMBOL_GPL() for snd_soc_rtdcom_lookup IIO: ADC: stm32-dfsdm: remove unused variable again ASoC: bcm2835: fix hw_params error when device is in prepared state ASoC: mxs-sgtl5000: Do not print error on probe deferral ASoC: sgtl5000: Do not print error on probe deferral ASoC: Intel: remove select on non-existing SND_SOC_INTEL_COMMON ALSA: usb-audio: Support changing input on Sound Blaster E1 ASoC: Intel: remove second duplicated assignment to pointer 'res' ALSA: hda/realtek - update ALC215 depop optimize ALSA: hda/realtek - Support headset mode for ALC215/ALC285/ALC289 ALSA: pcm: Fix trailing semicolon ASoC: add Component level .read/.write ASoC: cx20442: fix regression by adding back .read/.write ASoC: uda1380: fix regression by adding back .read/.write ASoC: tlv320dac33: fix regression by adding back .read/.write ALSA: hda - Use IS_REACHABLE() for dependency on input IIO: ADC: stm32-dfsdm: fix static check warning IIO: ADC: stm32-dfsdm: code optimization ...
