Merge tag 'asoc-v5.14' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v5.14

This release sees a nice new feature in the core from Morimoto-san,
support for automatic negotiation of DAI formats between the components
on the link.  Otherwise the big highlight was the merging of the Tegra
machine drivers into a single driver avoiding a bunch of duplication.

 - Support for automatic negotiation of DAI formats.
 - Accessory detection support for several Qualcomm parts.
 - Support for IEC958 control with hdmi-codec.
 - Merging of Tegra machine drivers into a single driver.
 - Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP
   i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm
   Quinary MI2S, Texas Instruments TAS2505
