This definition was introduced in this patch [1] that didn't land yet.
And you're removing it now. Could you sync with Jason and only
introduce the bits that are needed for your patches. Also all the
comments I made to the Jason's patch apply here.

Why do you need a second compatible, isn't this the same IP block? I
mean, I understand that you have 2 mmsys blocks, but both are the same
IP block, right? or are they different?
