IPU RGBA Overlays

I have a gstreamer plugin I was using on the I.mx53 to do video blending on the IPU using the overlay function which I've now ported to the I.mx6.  I am having an issue with the alpha channel though.  Using mxc_ipu_hl_lib I was able to have the overlays use the alpha channel within the RGBA image but this doesn't work anymore with the /dev/mxc_ipu interface.  I am applying an overlay over a live video and the overlay is generated in OpenGL/openvg so I do need that alpha channel and as we're trying to hit at least 720p it needs to use IPU or GPU without copies.
