Merge tag 'asoc-v6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v6.7 This is quite a large set of changes but mostly due to API cleanups and in driver specific ways rather than due to anything subsystem wide. Highlights include: - Standardisation of API prefixes on snd_soc_, removing asoc_. - GPIO API usage improvements. - Support for HDA patches. - Lots of work on SOF, including crash dump support. - Support for AMD platforms with es83xx, Awinc AT87390, many Intel platforms, many Mediatek platforms, Qualcomm SM6115, Richtek RTQ9128 and Texas Instruments TAS575x. [ the merge conflicts around SOF Intel HD-audio and CS35L41 subcodec drivers are resolved here -- tiwai ]
