Subject: icestick: fix UART flow control pins.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8acd09279946fd0e82951bcd708505bdc3fc0d86;p=nmigen-boards.git

icestick: fix UART flow control pins.

UART flow control pins match the signal names in the schematic, but
directions are reversed. Fix by setting role=dce.
