From 1d6e6e327162c6965c6007f9a46ce51086a7a458 Mon Sep 17 00:00:00 2001
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. Include bindings for the panels too.
The LTTD800480 L2RT is discontinued, but it may be in use by existing products.
Signed-off-by: Søren Andersen san@skov.dk Signed-off-by: Sam Ravnborg sam@ravnborg.org --- 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.
