[PATCH v3 1/2] dt-bindings: clock: qcom,videocc: Add sc8180x compatible

[Satya Priya Kakitapalli]

The sc8180x video clock controller block is identical to that
of sm8150. Add a new compatible string for sc8180x videocc and
use sm8150 as fallback.

This is not correct, does not match the compatibles - test yourself. You
want here contains.

Is there a need for this? Isn't it already covered by the SM8150 entry?

Yes and no. Yes - some change here is needed as I explained. No - this
exact change does not work, so it is obviously redundant.

Yes, I agree. I'll add 'contains:' throughout the schema and remove this 
compatible since anyway it matches with sm8150 compatible.

I checked this further and see that 'contains' is only needed for 
devices having multiple compatibles or using fallback.
Since we are not using the fallback for any of the other compatibles in 
this schema, I will add contains only for the sm8150 if/then block.
