[PATCH 0/2] Add support for Azoteq IQS7222A/B/C

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 common to 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.
