Reviewing this series, I think my input here has not been helpful or 
correct.

1. Declaring encoders/decoders in dts or yaml is wrong, accepted.

2. We can make a platform choice to hard-code that here in the
    platform declarations.

3. Remove the requirement from yaml for sc8280xp to declare decoder
    encoder

3. Profit.

Existing dtb all, literally all do the same thing first block decoder, 
second block encoder.

Rather than perform extensive surgery to venus to remediate the original 
yaml sin - hard-code decoder/encoder into platform code and deprecate 
the legacy over time.

Yes that means fixing to block 0 as decoder and block 1 as encoder but 
that is the defacto situation we have now, we may as well make it dejure.
