Subject is bogus. This is not SPI.

This is confusing. How is this device a SPI controller? You have
entirely different compatibles, so no, it's wrong. Missing ref to
spi-peripheral properties. See other bindings.

This does not match your previous bindings and nothing is explained in
commit msg.

You need constraints.

Drop description. ": true" instead

You did not test it.

?? No way. You do not have any children. Drop bogus properties and
explain it in commit msg.

No underscores in node names, generic node names, whatever this supposed

Test your bindings...
