Merge tag 'asoc-v6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.19 This is a very large set of updates, as well as some more extensive cleanup work from Morimto-san we've also added a generic SCDA class driver for SoundWire devices enabling us to support many chips with no custom code. There's also a batch of new drivers added for both SoCs and CODECs. - Added a SoundWire SCDA generic class driver, pulling in a little regmap work to support it. - A *lot* of cleaup and API improvement work from Morimoto-san. - Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm drivers. - Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290, QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806, TAS5815, TAS5828 and TAS5830. This also pulls in some gpiolib changes supporting shared GPIOs in the core there so we can convert some of the ASoC drivers open coding handling of that to the core functionality.
