[PATCH v3 0/5] Add polling mode to the MPR121 touchkey

This series is another attempt to use the MPR121 touch sensor
controller in polling mode. This version uses the brand new
input-poller API.

First of all, create a common input binding schema that assosiates some
existing input device properties.
In second step, convert the existing MPR121 freeform text binding into
a json-schema. Then the binding is enhanced with the poll-interval
property. The ability to work in the pollig mode is then added to the
mpr121_touchkey driver and enabled on a imx6dl-yapp4-hydra platform that
uses this controller.
