Echoing what others said, you're not making a DRM driver. The driver should
live outside
of the DRM code.
Actually, this sounds to me like "this should not be merged into linux kernel".
I mean,
we already have DRM API on Linux. We don't want another one, do we?
This driver doesn't have any display functionality.
And at the very least... this misses API docs for /dev/dxg. Code can't really
be reviewed without that.
The docs live here:
