Merge tag 'asoc-v6.5' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.5 A fairly quiet release from a core and framework point of view, but a very big one from the point of view of new drivers: - More refectoring from Morimoto-san, this time mainly around DAI links and how we control the ordering of trigger() callbacks. - Convert a lot of drivers to use maple tree based caches. - Lots of work on the x86 driver stack. - Compressed audio support for Qualcomm. - Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon, Ingenic X1000, Intel systems with various CODECs, Longsoon platforms, Maxim MAX98388, Mediatek MT8188, Nuvoton NAU8825C, NXP platforms with NAU8822, Qualcomm WSA884x, StarFive JH7110, Texas Instruments TAS2781.
