This series adds support for six-channel members of the Azoteq ProxFusion family of sensor devices: IQS620A, IQS621, IQS622, IQS624 and IQS625. Each device integrates multiple sensor technologies in a single package.
A multi-function device (MFD) driver supports core functions common to all devices, including device identification, firmware, interrupt handling and runtime power management. The MFD driver is also responsible for adding all product-specific sub-devices. Each device supports self-capacitive, Hall-effect, and (in some cases) mutual- inductive sensing. These functions represent keys or switches and are supported by an input driver that covers all five devices. An assortment of pwm, hwmon and iio drivers support device-specific functions. This series was tested using the following development hardware: IQS620AEV04, IQS621EV04, IQS622EV04 and IQS624/5EV04.
