Hi Roman.
you should use ./scripts/get_maintainer.pl to make sure you're cc'ing
the right people when posting patches. You should repost so that Jeff
has a copy of the patch to pick up (and add my acked-by when you do).

The DIU driver should bind against "fsl,mpc5121-diu"
directly. Add this compatible property to the match
table and fix DTS and platform code accordingly.

Could use a commit log. It is useful to give some details about what
this driver has been developed/tested on.
