Subject: [PATCH 59/59] drm/kmb: work around for planar formats
Date: Tue, 30 Jun 2020 14:28:11 -0700	[thread overview]
Message-ID: <1593552491-23698-60-git-send-email-anitha.chrisanthus@intel.com> (raw)
In-Reply-To: <1593552491-23698-1-git-send-email-anitha.chrisanthus@intel.com>

Set the DMA Vstride and Line width for U and V planes to the same as the
Y plane and not the actual pitch.
Bit18 of layer config does not have any effect when U and V planes are
swapped, so swap it in the driver.
