Hello angelogioacchino,

Thank you for your advice.

If I add a new compatible string inside of the mt6358 driver and dt-
bindings, then the machine driver which want to use mt6366 should
select SND_SOC_MT6358.

like below:

config SND_SOC_MT8186_MT6366_DA7219_MAX98357
	tristate "ASoC Audio driver for MT8186 with DA7219 MAX98357A
codec"
 	depends on I2C && GPIOLIB
 	depends on SND_SOC_MT8186 && MTK_PMIC_WRAP
 	select SND_SOC_MT6366   ==> SND_SOC_MT6358
	...

I just doubt it's enough to make sense. I originally wanted to put this
relationship in the sound/soc/codecs layer. So that this relationship
is not perceived by users(machine driver).
However, if the general practice is like this, I will adopt your
suggestion. Thank you again.
