Sorry I didn't know mt6359-codec and mt6358-sound are similar device
until Sept 26 (just yesterday) when I was reviewing the DT
bindings. Until I've found the previous DT Schema of mt6359-codec 
incorrect.
See [1] 
https://lore.kernel.org/linux-arm-kernel/20240926092519.6556-3-macpaul.lin@mediatek.com/T/
and [2] 
https://lore.kernel.org/all/20240926092519.6556-2-macpaul.lin@mediatek.com/

And.. I don't understand, the origin this patch v6 should be a text file
conversion, shouldn't we keep the origin content just a conversion and
trying not to broken other relate modules?

Please help to indicates what is a better approach here:

Should I merge the properties of mt6359-codec, mt6358-sound, and 
mt6397-codec
together and put them all into to mt6359.yaml and redo the converting of 
mfd/medaitek,mt6397.yaml?

That will be much simpler for the audio-codec node for mediatek,mt6397.yaml.
However there will be a little mismatch from the origin text file.

Thanks
