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.
