V3: doh! use dash, not underscore in node names. Wordsmith description.
V2: split Documentation/devicetree/bindings from driver patch
rename "atmel,atmegaxx_captouch" to "atmel,captouch" since it's irrelevant
which controller implements the register set/controller.
V1: posted https://lkml.org/lkml/2016/5/3/613
