From: Paul Mackerras Date: Thu, 22 Apr 2021 05:37:09 +0000 (+1000) Subject: arty: Change shield I/O pin bus into individual signals X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=84008fbf418b9b6307172c2b3a9d0fbd8e7f3d80;p=microwatt.git arty: Change shield I/O pin bus into individual signals Make the shield I/O pins be individual signals rather than a bus in order to avoid warnings on pins which don't have both a driver and a receiver.
