   12 description: |
   13   The Freescale i.MX8qm/qxp Pixel Combiner takes two output streams from a
   14   single display controller and manipulates the two streams to support a number
   15   of modes(bypass, pixel combine, YUV444 to YUV422, split_RGB) configured as
   16   either one screen, two screens, or virtual screens.  The pixel combiner is
   17   also responsible for generating some of the control signals for the pixel link
   18   output channel.
