Merge tag 'asoc-v6.18' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v6.18
A relatively quiet release for ASoC, we've had a lot of maintainance
work going on and several new drivers but really the most remarkable
thing is that we removed a driver, the WL1273 driver used in some old
Nokia systems that have had the underlying system support removed from
the kernel.
- Morimoto-san continues his work on cleanups of the core APIs and
enforcement of abstraction layers.
- Lots of cleanups and conversions of DT bindings.
- Substantial maintainance work on the Intel AVS drivers.
- Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
FourSemi FS2104/5S, Texas Instruments PCM1754.
- Remove support for TI WL1273.
