custom clocks

Hi,

I have ip cores that provide an axi-lite interface for control registers,
but which do not seem to make timing when that interface is connected to the
rfnoc_ctrl clock in an x310 design.

I read in the docs that from UHD 4.7 it is possible to define a new module
to create this clock, but it isn't clear how to implement this.

Is there perhaps an example that someone could share?

It would be first prize to generate a global clock that other of my rfnoc
blocks could use but I don't want to develop inside the UHD repo itself.

Many thanks, Kevin
