  # It's pretty scary, but the basic idea is that:
  #   - One node name can start with either s- or r- for PRCM nodes,
  #   - Then, the name itself can be any repetition of <string>- (to
  #     accomodate with nodes like uart4-rts-cts-pins), where each
  #     string can be either starting with 'p' but in a string longer
  #     than 3, or something that doesn't start with 'p',
  #   - Then, the bank name is optional and will be between pa and pg,
  #     pl or pm. Some pins groups that have several options will have
  #     the pin numbers then,
  #   - Finally, the name will end with either -pin or pins.
