So from the perspective of the dbcool driver, it's never a known value and would need to be configured in all cases when the ATD7490 is used.
Does the CPU know it? If it does all you need is an interface for this driver to ask, or, since it seems to be a constant, make the CPUs put their Tcc values at a known location where your driver can pick them up.
have fun Michael
