Subject: [PATCHv1 07/14] drm/omap: add support for physical size hints from display drivers
Date: Mon, 24 Jul 2017 19:33:04 +0200	[thread overview]
Message-ID: <20170724173311.27170-8-sebastian.reichel@collabora.co.uk> (raw)
In-Reply-To: <20170724173311.27170-1-sebastian.reichel@collabora.co.uk>

While physical size information is automatically parsed for EDID
based displays, we need to provide it manually for displays providing
one fixed mode.
