7 title: Integrator/AP Logic Module extension bus
10   - Linus Walleij <linusw@kernel.org>
15   determine if a logic module is connected at index 0, 1, 2 or 3. The logic
16   module connector is described in this binding. The logic modules per se
17   then have their own specific per-module bindings and they will be described
18   as subnodes under this logic module extension bus.
