Add support for audio on the Kaanapali MTP platform by introducing device
tree nodes for WSA8845 smart speaker amplifier for playback, DMIC
microphone for capture, and sound card routing. The WCD9395 codec is add
to supply MIC-BIAS, for enabling onboard microphone capture.

I didn't understand this, Could you please help me to provide more context on it?
Is this regarding Audio over Type-c?
It's simply incomplete
picture which is wrong for case of submitting everything at once.
Either you release early, release often (which I asked you many
times), or you submit complete work.
These patches enable usecase for Speaker playback and On-board-Mic
Capture. Do you consider is there is anything need to do to make it complete ?
You don't understand how your own SoC is organized and create fake
split and inflated patch count just, as someone admitted, to have LWN
stats.
This work is incomplete, so please start organizing patches per
logical features, not per your patch count and company KPI
.
NAK, incomplete patch and previously communicated as non working
Earlier there is an issue with SWR-TX interrupt configuration so did not work. As i fixed/configured
interrupt, it worked and validated on Kaanapali-MTP.
Thanks,
Prasad
