This is a series of patches for alsa-lib to add the support of MIDI
2.0 features, corresponding to the kernel patches that have been
submitted recently:
https://lore.kernel.org/r/20230519093114.28813-1-tiwai@suse.de
The API extensions are minimalistic, and only a few basic accessors
have been defined.

[PATCH] ALSA: ti: Use pcm_for_each_format() macro for PCM format iteration
by Min-Hua Chen 19 May '23
by Min-Hua Chen 19 May '23
19 May '23
Use pcm_for_each_format for the PCM format iteration and fix the
following sparse warnings.
sound/soc/ti/davinci-mcasp.c:1336:26: sparse: warning: restricted snd_pcm_format_t degrades to integer
sound/soc/ti/davinci-mcasp.c:1358:26: sparse: warning: restricted snd_pcm_format_t degrades to integer
sound/soc/ti/davinci-mcasp.c:1438:26: sparse: warning: restricted snd_pcm_format_t degrades to integer
No functional changes.

This patch chain adds support for the Cirrus Logic cs42l43 PC focused
SoundWire CODEC. Some supporting work is included in the chain,
including adding an ASoC control notification helper function and
adding support for IRQs generated by the in-band SoundWire alert
mechanism.
The chain is currently based of v6.4-rc1 because I am not 100% sure
which tree we want to send everything through. The CODEC support
has a build dependency on both the SoundWire change and the ASoC
soc-component change.
Thanks,
Charles
