that should still be *inside* the PLL block, correct?  i.e. the *PLL block*
should use the standard cell library and should use a MUX and buffers, yes?

i.e. this should be done by Dmitri.

the LibreSOC core (and litex peripherals) will *only* take the one clock, and
the one clock shall be the PLL's output, correct?  LibreSOC's core (and
peripherals) shall *NOT* try to do the MUX, correct?
