If the blocks are truly 1:1 shared, with no additional software changes
required, please still include a 8180-specific compatible in the front,
with a 8150 fallback:

"qcom,sc8180x-videocc", "qcom,sm8150-videocc"

which will require a dt-bindings update

I did not add this manually, seems it was appended by b4

https://b4.docs.kernel.org/en/latest/contributor/prep.html#what-if-the-series-only-has-a-single-patch


I have already mentioned the same message in the commit text above my 
sign-off.

Sure, I will add the new compatible for sc8180x and update the bindings.

Why are you adding the same multiple times? This was added A YEAR AGO,
so you clearly send us some complete outdated ancient tree!

It seems like you're confusing something, there is no videocc node in
sc8180x.dtsi

Heh, I am... the line below:
	compatible = "qcom,sm8150-videocc";
confused me and I looked at wrong file.

Satya:
Still for obvious reasons: NAK. See writing bindings or internal guideline.

Sure, I will add a new compatible for sc8180x and update the bindings 
accordingly in my next post.
