Merge tag 'asoc-v6.9' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.9 This has been quite a small release, there's a lot of driver specific cleanups and minor enhancements but hardly anything on the core and only one new driver. Highlights include: - SoundWire support for AMD ACP 6.3 systems. - Support for reporting version information for AVS firmware. - Support DSPless mode for Intel Soundwire systems. - Support for configuring CS35L56 amplifiers using EFI calibration data. - Log which component is being operated on as part of power management trace events. - Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
