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
