By data sheet, do you mean documentation from Synopsis, or is this an
internal document? Assuming the hardware engineers have not hacked up
the Synopsis IP too much, the Synopsis documentation is probably the
most accurate you have.

Do you know if this is specific to Intels integration of the Synopsis
IP, or this is part of the core licensed IP?

We need to understand when we need a quirk because intel did something
odd, or it is part of the licensed IP and should happen for all
devices using the IP.
