Takashi Iwai a98a9c11a3 ASoC: Updates for v6.15 
This is a very big release due to a combination of some big new work,
 mainly new drivers and generic SoundWire support, and some wide ranging
 cleanup work that made small changes to a lot of drivers.
 
  - Morimoto-san has completed the conversion to use modern terminology
    for the clocking configuration, and several other cleanups with
    narrower impact.
  - All the power management operation configuration was updated to use
    current idioms by Takashi Iwai.
  - Clarification of the control operations from Charles Keepax.
  - Prepartory work for more generic SoundWire SCDA controls from Charles
    Keepax.
  - Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
    PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95, nVidia
    Tegra interconnects, Rockchip RK3588 S/PDIF, Texas Instruments
    SN012776 and TAS5770L, and Wolfson WM8904 DMICs,
 
 Some changes from the tip tree adding APIs needed by the AMD code are
 included, these were unfortunately rebased in the tip tree after being
 pulled in.  There's also some regmap changes supporting the SCDA work
 and some devres refactoring that was pulled in to support other changes.
