Yes, I see by moving this property into the allOf its only applicable for compatible "amd,pensando-elba-spi". Also changing "enum:" to "const:" as shown. Yes on the DT-bindings check. Rob Herring's bot indicated an error but I had none in checking V6 patchset. I did a dtschema update and it went from dtschema 2022.3.2 to dtschema-2022.8.3 and will see if that is the reason.
