[PATCH 0/6] Add YUV formats support to dmabuf, and a v4l2 client

[Emmanuel Gil Peyrot]

This series makes the gl-renderer accept the YUYV, NV12 and YUV420
dmabuf formats using the existing shader path.  There is no
implementation in pixman-renderer, nor any drm passthrough in case the
hardware supports this.

It also adds a new client, weston-simple-dmabuf-v4l, which retrieves
dmabuf fds from V4L2 and sends them to the compositor.  It supports
both single- and multi-planar v4l2 APIs, and was tested against both
the uvcvideo and the vivid module in Linux 4.2 and 4.3.

I also renamed the old Intel-specific simple-dmabuf to
simple-dmabuf-intel, and fixed a few deficiencies found during the
development of simple-dmabuf-v4l.

Emmanuel Gil Peyrot (6):
  linux-dmabuf: Move the attributes part of linux_dmabuf_buffer into its
    own struct
  gl-renderer: introduce a new struct dmabuf_image
  gl-renderer: Add support for a few YUV dmabuf formats
  clients: rename simple-dmabuf into simple-dmabuf-intel
  clients: Fix a few issues in simple-dmabuf-intel
  clients: add simple-v4l-dmabuf client
