Merge tag 'asoc-v6.8' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.8 This is a relatively quiet release, there's a lot of driver specific changes and the usual high level of activity in the SOF core but the one big core change was Mormioto-san's work to support more N:M CPU:CODEC mapping cases. Highlights include: - Enhanced support for N:M CPU:CODEC mappings in the core and in audio-graph-card2. - Support for falling back to older SOF IPC versions where firmware for new versions is not available. - Support for notification of control changes generated by SOF firmware with IPC4. - Device tree support for describing parts of the card which can be active over suspend (for very low power playback or wake word use cases). - ACPI parsing support for the ES83xx driver, reducing the number of quirks neede for x86 systems. - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm SM8250, SM8550, SM8650 and X1E80100. - Removal of Freescale MPC8610 support, the SoC is no longer supported by Linux.
