Hi Daniel

Thank you for contacting me

Or having extra flag for it ?

	static const struct of_device_id simple_of_match[] = {
		{ .compatible = "simple-audio-card", },
		{ .compatible = "simple-scu-audio-card",
		  .data = (void *)DPCM_SELECTABLE },
+		{ .compatible = "simple-xxx-audio-card",
+		  .data = (void *)DPCM_WITH_PLATFORM },
		{},
	};

This idea is adding new feature on simple-card.
But, in sound card case, many patterns exist,
thus, adding new feature into simple-card will be difficult.

So having new file is not bad idea.
But, I'm thinking some Card driver want to create new driver,
but want to share simple-card code.
Actually, simple-card-utils.c is for it.
But, maybe someone want to share simple-card.c code itself ?

Some overwrite technic can be nice idea.

# Now I'm focusing cleanup ALSA SoC
# Current framework has "normal sound" and "DPCM sound",
# and it makes code/DT difficult.
# But if all cleanup could be done, these can be merged,
# and can have more flexible connection.
# Then, I want to create new simple-card with *really* simple code :)

Thank you for your help !!
Best regards
