Add TC9594, from the software point of view this is identical to
TC358768 with the main difference being automotive qualified.

If it is the same, why they are not compatible? I got only three patches
out of six, thus I cannot check by myself. Please explain.

Best regards,

I assume I am not understanding something very basic ...

The register description and SW functionality of all these 3 parts is
identical.

How should be the compatible described in the DT schema in this case?

Here the whole series: https://lore.kernel.org/all/20230330095941.428122-1-francesco@dolcini.it/

Do you want to me to send the whole series and not just the DT binding
next time? Happy to do it, if you prefer.

Francesco

Look at any board compatibles for example.

So NAK on 4th patch. Don't grow device ID tables needlessly.
