Subject: [PATCH 09/18] drm/armada: add drm_mode_set_crtcinfo() mode fixup
Date: Thu, 13 Jun 2019 16:02:28 +0100	[thread overview]
Message-ID: <E1hbRFE-00007h-BQ@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20190613150114.xqkyb7j7w4ve4yvr@shell.armlinux.org.uk>

Add a drm_mode_set_crtcinfo() call in our CRTC's mode_fixup callback
to ensure that any adjustments to the mode made by connectors etc are
properly accounted for by the CRTC.
