From c8b309b53d6739b91d81311e4228f66f31c894f1 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Tue, 28 Apr 2020 18:19:48 +0100 Subject: [PATCH] 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.
