I still give my RB for the series.

To me the only question is should it be applied to sm8550 or to new SoCs 
from now on, sa8775p, x1e and derivatives.

I take the point on ABI breakage on 8550, so to me it seems fully 
consistent with Krzysztof's statements on ABI maintenance and indeed the 
need to expand the features of this driver to do so from the next 
submission onwards.

That can be as simple as

schema.yaml

if compatible newsoc
     minItems:1
     maxItems:2

8550's ABI is stable and new SoC submissions will support the 
secure/non-pixel method.
