Subject: [PATCH 2/3] uapi: drm: New fourcc codes needed by Xilinx Video IP
Date: Mon, 27 Nov 2017 18:27:32 -0800	[thread overview]
Message-ID: <1511836053-9489-3-git-send-email-hyun.kwon@xilinx.com> (raw)
In-Reply-To: <1511836053-9489-1-git-send-email-hyun.kwon@xilinx.com>

From: Jeffrey Mouroux <jmouroux@xilinx.com>

The Xilinx Video Mixer and 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.
