Hey Walker,

Is this one of these waveshare things + a visionfive 2?
https://www.waveshare.com/wm8960-audio-hat.htm

I'm a bit lost as to why this needs a whole new board, should it not
just be an overlay that you can apply to the existing dts?

Taking this to an extreme, should I expect to see a new devicetree for
everything RPi hat that you decide to use with a VisionFive 2?

Also, it'd be nice to provide a Link: to where someone can find more
info on this combination of items. Google for "wm8960 visionfive 2"
gives me nothing, nor does "starfive audio card" etc.

Thanks,
Conor.

Hey Conor,
I'm glad to receive your comments.

Now we are using this board + VisionFive2 :

For your response, I did some thinking. Because wm8960 codec is not integrated
 on the VisionFive2 board, perhaps using overlay is a better way.

Aye. I think so too. From my PoV, if this particular seeed audio board
is something you're bundling with VisionFive 2 boards on your storefront
etc, then I'm fine with taking it as an in-tree overlay.
If it is just a "random" RPi hat (that happens to be exactly what you
need for testing the audio drivers), then I don't know where to draw a
line for what is & what is not acceptable for inclusion.

In both cases, it's Emil's call.

Cheers,
Conor.

I'm not aware of any shop bundling the VF2 with an audio board. I
agree: please don't add device trees for combinations of VF2s and
hats. That should be an overlay.

Since you guys agree, so let's do it this way.
