Subject: [PATCH 4/6] drm/imx: support handling bridge timings bus flags
Date: Tue, 4 Sep 2018 22:21:11 -0700 [thread overview]
Message-ID: <20180905052113.21262-4-stefan@agner.ch> (raw)
In-Reply-To: <20180905052113.21262-1-stefan@agner.ch>
A bridge might require specific settings for the pixel data on
the bus. Copy the bus flags from the bridge timings if a bridge
is in use.
