Subject: ath79: fix RS-485 on Teltonika RUT-955
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=53a7d5d614050a38a4e78f5a9e153e7612d587f0;p=openwrt%2Fstaging%2Fadrian.git

ath79: fix RS-485 on Teltonika RUT-955

DTR GPIO isn't actually needed and triggers boot warning.
TX pin was off by one (GPIO 19 instead of GPIO 18).

Reported-by: @tophirsch
Fixes: d1130ad265 ("ath79: add support for Teltonika RUT955")
