So imx8mm is compatible with imx7d, and imx7d is compatible with imx6q, 
but imx8mm is not compatible with imx6q? That doesn't really make sense. 
Maybe all 3 compatibles makes sense, but only if s/w understanding only 
one of the fallback compatibles would function without knowledge of the 
newer h/w.

Please mark this as deprecated. If it is always 1 cell, then there's no 
point.

And drop as required. That all can be a follow-up patch if you prefer or 
in this patch is fine. Primarily, I don't want this pattern copied.

I added the list according the current device tree in use. If using
three compatibles,  that would involve device tree upate, and firmware
update for SR-IR.

My understanding is imx8mm is compatible with imx7d, imx7d is compatible
with imx6q, then imx8mm is compatible with imx6q. it is just not put
them under one item. Please correct if my understanding is wrong.

Do you have any guidance here? I am not sure how to proceed on V4.
