Subject: [PATCH] drm: panel: simple: add Toshiba LT089AC19000
Date: Fri, 13 Oct 2017 19:01:27 +0200	[thread overview]
Message-ID: <20171013170127.16042-1-l.stach@pengutronix.de> (raw)

Only exposes a single mode and not a complete display timing, as
the datasheet is rather vague about the minimum/maximum values.
