Hello Trevor, thanks for the patch! However, there's something to improve...

We can at least partially reuse existing UCM2 configuration if you slightly change the names for these controls.

Specifically, MAX98090 (yes I know it's a different codec) has names "Speaker Left", "Speaker Right" instead, we will be able to at least partially reuse these (or get uniform naming, which is still good). As for the "Headphone Jack", it's simply "Headphone".

Please note that the actual control names in userspace will be, exactly,

"Speaker Left Switch", "Speaker Right Switch", "Headphone Left Switch", "Headphone Right Switch"...

And I won't go on repeating the same thing over and over again. I think that the best idea here is to either create a mt8195-mt6359-rt5682-common.c file, or to rename the others to something else and get them all in the same file.
