Merge tag 'asoc-v6.6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.6 The rest of the updates for v6.6, some of the highlights include: - A big API cleanup from Morimoto-san, rationalising the places we put functions. - Lots of work on the SOF framework, AMD and Intel drivers, including a lot of cleanup and new device support. - Standardisation of the presentation of jacks from drivers. - Provision of some generic sound card DT properties. - Conversion oof more drivers to the maple tree register cache. - New drivers for AMD Van Gogh, AWInic AW88261, Cirrus Logic cs42l43, various Intel platforms, Mediatek MT7986, RealTek RT1017 and StarFive JH7110.
