Merge tag 'sound-4.7-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull more sound updates from Takashi Iwai:
 "This is the second update round for 4.7-rc1.  Most of changes are
  about the pending ASoC updates and fixes, including a few new drivers.
  Below are some highlights:

  ASoC:
   - New drivers for MAX98371 and TAS5720
   - SPI support for TLV320AIC32x4, along with the module split
   - TDM support for STI Uniperf IPs
   - Remaining topology API fixes / updates

  HDA:
   - A couple of Dell quirks and new Realtek codec support"
