Merge tag 'asoc-v5.18' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v5.18 Quite a quiet release for ASoC, lots of work on drivers and platforms but nothing too groundbreaking but not much on the core itself: - Start of moving SoF to support multiple IPC mechanisms. - Use of NHLT ACPI table to reduce the amount of quirking required for Intel systems. - Some building blocks for use in forthcoming Intel AVS driver for legacy Intel DSP firmwares. - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas RZ/V2L, Texas Instruments TAS585M
