Subject: [PATCH 3/3] drm/panel: ltk500hd1829: add panel type for ltk101b4029w
Date: Thu, 15 Feb 2024 10:05:15 +0100 [thread overview]
Message-ID: <20240215090515.3513817-4-heiko@sntech.de> (raw)
In-Reply-To: <20240215090515.3513817-1-heiko@sntech.de>
From: Heiko Stuebner <heiko.stuebner@cherry.de>
The ltk101b4029w ist a 10.1 inch DSI panel and shares the same supplies
and startup timings with the existing ltk500hd1829.
So simply add it as a variant with its own init sequence and display-mode.
