Need to add below line here, right?
+          - const: qcom,sm8550
> Missing compatible. Please read previous discussions.
The previous comments was missed. Just double confirm here for 
"fallback" meaning here.

Could you pls also double confirm for my understandings for the 
compatible rules?
As long as sm8550 was designed "hardware compatible"(pin-to-pin 
compatible) and "software firmware compatible"(firmware also support 
sm8550) to qcs8550, it is request to add compatible sm8550 to current 
compatible sequence like: board/SOM/soc/base soc.

Note that, we don't really have hardware like "sm8550 inside aim300".
