Subject: drm/vc4: Fix the "no scaling" case on multi-planar YUV formats
From: Boris Brezillon <boris.brezillon@bootlin.com>
X-Patchwork-Id: 240917
Message-Id: <20180725122907.13702-1-boris.brezillon@bootlin.com>

When there's no scaling requested ->is_unity should be true no matter
the format.
Also, when no scaling is requested and we have a multi-planar YUV
format, we should leave ->y_scaling[0] to VC4_SCALING_NONE and only
set ->x_scaling[0] to VC4_SCALING_PPF.
Doing this fixes an hardly visible artifact (seen when using modetest
and a rather big overlay plane in YUV420).
Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")
