For a new SoC family, I would strongly suggest using a renesas,cpg-mssr
based binding instead:
  - No more mstp*_clocks nodes with array triplets to keep in sync,
  - Support for MSSR reset can be added later,
  - No need to add all those fixed-factor clocks to DT,
  - Less DT churn when adding support for new devices.

when I'm talking to journalists I just say "programmer" or something like that.
