Yes I've been wondering about that too. Let's just move it over to the
bridge node? We could produce a warning if the dsi host node has the
data-lanes property.. No current in kernel users AFAIK.

FYI, for omapdrm, we already have a legacy dt property "lanes" for the
wiring that tells number of lanes used and the order of the lanes.

Tony
