Subject: renaming params.py to parse.py. Adding checks on input
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=445782ffd34ed8dc35fc12319d5eb0aff1db535e;p=pinmux.git

renaming params.py to parse.py. Adding checks on input

See #3.

Added check to see if muxed lists and dedicated lists do not have any duplciates.  This can simulated by replacing uart1_tx to uart2_tx in pinmap.txt.
