Have you considered teaching the DRI loader about this? Unlike the
tegra driver there's nothing special going on here.
Create a dumb buffer on the DC, export as dmabuf and let the GPU draw into it.

Perhaps with we can have some code for the DC <> GPU mapping and at
later stage move it to an external file.
This way adding new combinations will be trivial addition to that,
instead of having yet another driver.
