I've not spent the time to fully understand the code, so i could be
very wrong....

From what you said above, you clock is fixed? So maybe you can do
something like:

mfld_get_clk_rate_khz()

https://elixir.bootlin.com/linux/latest/source/drivers/i2c/busses/i2c-designware-pcidrv.c#L97

How are you instantiating the driver? Can you add to
i2_designware_pci_ids[]?
