# 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.
