ASoC: Updates for v6.2
This is a fairly sedate release for the core code, but there's been a
lot of driver work especially around the x86 platforms and device tree
updates:
- More cleanups of the DAPM code from Morimoto-san.
- Factoring out of mapping hw_params onto SoundWire configuration by
Charles Keepax.
- The ever ongoing overhauls of the Intel DSP code continue, including
support for loading libraries and probes with IPC4 on SOF.
- Support for more sample formats on JZ4740.
- Lots of device tree conversions and fixups.
- Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
Rockchip RK3588
There's more cross tree updates than usual, though all fairly minor:
- Some OMAP board file updates that were depedencies for removing their
providers in ASoC, as part of a wider effort removing the support for
the relevant OMAP platforms.
- A new I2C API required for updates to the new I2C probe API.
- A DRM update making use of a new API for fixing the capabilities
advertised via hdmi-codec.
Since this is being sent early I might send some more stuff if you've
not yet sent your pull request and there's more come in.
