From: =?UTF-8?q?S=C3=B8ren=20Andersen?= san@skov.dk Date: Thu, 30 Aug 2018 20:48:57 +0200 Subject: [PATCH 1/1] panel-simple: add LOGIC Technologies panels MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
Add support for the following panels from LOGIC Technologies, Inc: - LTTD800480070-L2RT - LTTD800480070-L6WH-RT
Include a new vendor prefix for LOGIC Technologies Inc.
The LTTD800480070-L2RT is discontinued, but it may be in use by existing products.

The From: line looks a bit suspicious with the UTF-8 stuff, but applying the patch here with "git am" resulted in a proper author with the correct dansih character "ø".
If a specific binding file is required for each panel please let me know and I will add them.
Sam
