+ # 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.
