These bindings here: https://lore.kernel.org/all/20221118181826.28269-2-quic_molvera@quicinc.com/
I believe you commented that we either have these clocks or we don't, correct? I added them to
the dt since these clocks exist and will be needed later when USB and PCIE nodes are added.
As Konrad noted, these technically belong in the PHYs, but I was told to put stub fixed
clocks instead here: https://lore.kernel.org/lkml/2c8c4642-8aee-3da3-7698-5e08b4c5894d@linaro.org/

How is this to be handled? Should I remove the clocks from the dt and the bindings and add them
later when we need them? Do I leave stub clocks here with frequency 0 until needed? I am
very confused right now.

Thanks,
Melody
