History
Marius Strobl d5e0798e6d All of Oxford/PLX OX16PCI954, OXm16PCI954 and OXu16PCI954 share the 
exact same (subsystem) device and vendor IDs. However, the reference
design for the OXu16PCI954 uses a 14.7456 MHz clock (as does the EXSYS
EX-41098-2 equipped with these), while at least the OX16PCI954 defaults
to a 1.8432 MHz one. According to the datasheets of these chips, the
only difference in PCI configuration space is that OXu16PCI954 have
a revision ID of 1 while the other two are at 0. So employ the latter
for determining the default clock rates of this family.
Note that one might think that the actual clock could be derived from
the Clock Prescaler Register (CPR) of these chips. Unfortunately, this
is not that case and its use and content are orthogonal to the frequency
of the crystal employed.
Tested with an EXSYS EX-41098-2, which identifies and attaches as:
