From a6a00918d4ad8718c3ccde38c02cec17f116b2fd Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Tue, 24 Jul 2018 15:36:01 +0200 Subject: drm/vc4: Reset ->{x, y}_scaling[1] when dealing with uniplanar formats This is needed to ensure ->is_unity is correct when the plane was previously configured to output a multi-planar format with scaling enabled, and is then being reconfigured to output a uniplanar format. Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")
