This series introduces support for the Azoteq IQS7222A, IQS7222B and IQS7222C capacitive touch controllers. This new family of devices is similar to the IQS269A, a key difference being the delineation between conversion cycles and sensing channels. A cycle represents the charge transfer mechanism shared by up to two channels. Channels may represent keys or switches and have two levels of detection (proximity and touch). Each device has its own unique features including channel count, slider or wheel support, and Hall-effect sensing. The driver is demonstrated with each device in the following videos: IQS7222A: https://youtu.be/SyHhe9pSr8c IQS7222B: https://youtu.be/R9Yd8yFPmN8 IQS7222C: https://youtu.be/-ahg52Co5zo Like the IQS269A and its close cousin IQS626A, the IQS7222A/B/C are highly configurable and follow the same general structure in terms of how their bindings are represented.
