So depending on whether they use an FPGA or an ASIC the values are
different, no matter what frequency (50 or 66 MHz) is used. So it is not
derived from frequency.

So I think it makes most sense to have it in the device tree as we don't
know what designs are out there.

I still would prefer to keep timing values private to the driver and just
select the controller type (FPGA/ASIC) using the device tree.

OK I'll revert to static timings in the driver, no problem.
