have removed vendor-prefix from v1>v2 based on suggestion this can be useful for other vendors too.

but last 3 patches of this series replacing bifurcation property (which is only bool) by the more useful lane-map (left alone for discussion, will be squashed if the right way is found).

i guess same here, description+type needed, but how to describe an array of int in yaml? do you know any examples?
