Subject: [PATCH AUTOSEL 4.18 39/45] drm: rcar-du: Update Gen3 output limitations
Date: Sun, 4 Nov 2018 08:52:34 -0500 [thread overview]
Message-ID: <20181104135240.88431-39-sashal@kernel.org> (raw)
In-Reply-To: <20181104135240.88431-1-sashal@kernel.org>
From: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>
[ Upstream commit 2a3181d9cfd6d5aa48f8527708d0c32072072cef ]
The R-Car Gen3 DU utilises the VSP1 hardware for memory access. The
limits on the RPF and WPF in this pipeline are 8190x8190.
Update the supported maximum sizes accordingly.
