Merge tag 'asoc-v6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
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.
