Subject: [PATCH v1 1/2] uapi: drm: Add fourcc codes needed by Xilinx Video IP
Date: Fri, 4 Aug 2017 11:49:02 -0700	[thread overview]
Message-ID: <1501872543-28352-2-git-send-email-jmouroux@xilinx.com> (raw)
In-Reply-To: <1501872543-28352-1-git-send-email-jmouroux@xilinx.com>

The Xilinx Video Mixer andn Xilinx Video Framebuffer DMA IP
support video memory formats that are not represented in the
current DRM fourcc library.  This patch adds those missing
fourcc codes.
