that the kernel version and the gpu library need to match (correct me if
I'm wrong).  This would mean that if either the kernel or imx-gpu-viv are
updated without the other, things may not work properly at run-time.  I
expect that the X-windows driver also needs to match the others.  So, no
matter the order of the patches, run-time will be broken between some
patches until others have been applied.

The difference is that there is nothing you can do about the VPU whereas
the graphics libraries always match the kernel module which can be built
against any kernel >= 3.10.53.

Also I don't mind the order that much, it is just that it makes more sense
to have graphics patches together and multimedia one on their own as they
are not dependent on each other.

Yes that looks good to me.
