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.

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.

Add bt-sco sound card, which is used by BT HFP case.
It supports wb profile as default.
