Merge tag 'sound-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "As shown in diffstat and logs, it was again a busy development cycle
  at this time, too. The most significant changes are still on-going
  refactoring / modernization works for ASoC core and drivers, but there
  are lots of other changes as well. Here we go, some highlights below:

  ASoC:

   - Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
     them are systematic, but also including cleanups and modernization

   - A bulk of updates for some ASoC platforms, Freescale, sunxi and
     Intel SST/SOF

   - Initial support for Sound Open Firmware on i.MX8

   - Removal of deprecated w90x900 and nuc900 drivers

   - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
     7ULP and 8MQ, Meson G12A and NXP UDA1334

  USB-audio:

   - More validations of descriptor units for hardening against bugs
     reported by fuzzers

   - PCM device assignment workaround for a past call-order change

   - Scarlett Gen2 mixer interface, a few more more quirks

  HD-audio:

   - Support for audio component with AMD/ATI and Nvidia HDMI codecs

   - Clean up HD-audio core and remove indirect access ops for Intel SOF

   - DMIC detection at probe; it would make systems automatically
     falling back to SST/SOF driver on devices that need DMIC handling.
     Needs a new Kconfig to set, and beware that it's still new and a
     bit experimental

  FireWire:

   - Lots of code refactoring and cleanups"
