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.
Include bindings for the panels too.
The LTTD800480 L2RT is discontinued, but it may be in
use by existing products.

v2:
Checked several simple panels, all had a bindings file.
So my assumption about simple panels not requiring a binding was wrong.
Thus added the bindings, no other changes.
