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
