Yes, some WiFi/BT bits (with LVDS if OF used), but the idea of having
separate dtsi is as per the Engicam's hardware topology. C.TOUCH2.0 is
a Carrier board like EDIMM2.2 and each as its own purpose and possible
to use or update as per customer needs. Maintaining separate dtsi
files for a carrier board will easy for customers to use the same SOM
and create their own carrier hardware. This was the customers can just
add their own custom carrier and reuse existing topoply in Mainline.

Hope you understand, the structure of these dtsi files.

Jagan.
