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.
