From 49785e25816b0567112ba599504c3b78901a7db4 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 9 Dec 2014 22:45:11 +0200 Subject: [PATCH] drm: rcar-du: Configure pitch for chroma plane of multiplanar formats The PnMWR register containing the plane stride must be programmed with correct stride values for both the luma and chroma planes when using a multiplanar format. Fix it.
