+
+description: The Integrator/AP is a prototyping platform and as such has a
+ site for stacking up to four logical modules (LM) designed specifically for
+ use with this platform. A special system controller register can be read to
+ determine if a logical module is connected at index 0, 1, 2 or 3. The logical
+ module connector is described in this binding. The logical modules per se
+ then have their own specific per-module bindings and they will be described
+ as subnodes under this logical module extension bus.

This adds YAML device tree bindings for the Integrator/AP logical modules. These are plug-in tiles used typically for FPGA prototyping.
