Please add the "amd,pensando-elba-syscon" property definition as I
asked here:

No. What Krzysztof and I asked was to add the property definition
into the allOf: [ if ..., ] statement. Please read more carefully my
last comment:
https://lore.kernel.org/lkml/20220704131810.kabkuy6e4qmhfm3n@mobilestation/
The definition is supposed to look like this:

* Please also note that I've replaced "enum:" with "const:" in the if
statement above.
The difference with what you suggested is that my version is
applicable for the Pensando ELBA SPI controller only, while your
update will cause applying the "amd,pensando-elba-syscon" property
constraints for all DW SSI controllers which isn't what we would want.

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.
