Merge tag 'asoc-v5.19' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v5.19 This is quite a big update, partly due to the addition of some larger drivers (more of which is to follow since at least the AVS driver is still a work in progress) and partly due to Charles' work sorting out our handling of endianness. As has been the case recently it's much more about drivers than the core. - Overhaul of endianness specification for data formats, avoiding needless restrictions due to CODECs. - Initial stages of Intel AVS driver merge. - Introduction of v4 IPC mechanism for SOF. - TDM mode support for AK4613. - Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces, nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
