These shouldn't be needed, just declare the device as the same as what

We should have SoC specific compatibles so that any further quirks or
incompatibilities can be easily addressed.

"further" work on quirks or incompatibilities can be added when they are
found and needed.  We don't add stuff for no good reason to the kernel.

It's not only the IP itself
that can differ, it's also the integration of the IP into the final
product that could have an influence on the behavior.

This is for the Pixel 6, a device that is no longer even shipping.  The
"final product" is long stable, so this should not be an issue.

thanks,

greg k-h
