Subject: [PATCH 06/18] drm/armada: move plane address and pitch calculation to atomic_check
Date: Thu, 13 Jun 2019 16:02:12 +0100	[thread overview]
Message-ID: <E1hbREy-00007L-OE@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20190613150114.xqkyb7j7w4ve4yvr@shell.armlinux.org.uk>

Move the plane address and pitch calculations to atomic_check rather
than the update function, so we don't have to probe the interlace
setting for the CRTC while updating the plane.

Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
