[PATCH v2 6/6] arm64: dts: imx943-evk: Add PDM microphone sound card support

[Shengjiu Wang]

Add PDM micphone sound card support, configure the pinmux.

This sound card supports recording sound from PDM microphone and convert
the PDM format data to PCM data.

Out of curiosity did you considered making use of "audio-graph-card2"?

The "fsl,imx-audio-wm8962" seems like a pretty simple sound card which
could be added via the "audio-graph-card2" as well. Don't get me wrong,
it's not wrong what you're doing here but making use of the generic
sound card would be nice because it's very common to just copy'n'paste
the audio integration from the corresponding evk.dts file.

Regards,
  Marco

Thanks for the suggestion.

WM8962 has a function .set_pll(), which hasn't been supported in
audio-graph-card2.  so we still use fsl,imx-audio-wm8962.
