From: Daniel Golle Date: Tue, 28 Apr 2020 17:19:48 +0000 (+0100) Subject: ath79: split Teltonika RUT955 to support other RUT9xx models X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c8b309b53d6739b91d81311e4228f66f31c894f1;p=openwrt%2Fstaging%2Fjogo.git ath79: split Teltonika RUT955 to support other RUT9xx models Split device-tree of Teltonika RUT955 into a generic RUT9xx part and a part specific to that version of RUT955 already supported. Also harmonize GPIO and LED names with what is used by the vendor firmware and assign RS485 DTR signal.
