ID:21197 LVDSIN port of LVDS DPA atom "<name>" must be fed by input pin that does not feed any other logic

CAUSE: The LVDSIN port of the specified LVDS DPA atom is driven by something other than an input pin that does not feed any other logic. However, an input pin that does not feed any other logic must feed the LVDSIN port of the LVDS DPA atom.

ACTION: Modify the design so an input pin that does not feed any other logic drives the LVDSIN port of the LVDS DPA atom.
