[PATCH 0/6] Add support for slider gestures and OTP variants

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

 



This series introduces support for some additional features offered by the
Azoteq IQS269A capacitive touch controller.

Patches 1 and 2 add support for slider gestures (e.g. tap or swipe). Gestures
are recognized by the hardware itself based on touch activity across the chan-
nels associated with the slider. This feature is useful for lightweight systems
that do not post-process absolute coordinates to determine gestures expressed
by the user.

Gestures are presented to user space as keycodes. An example use-case is an
array of multimedia keys as seen in the following demo:

Patches 3 and 4 add support for the device's available OTP variants, which
trade features or exhibit errata that require workarounds. Patches 5 and 6
comprise minor fixes and are included in the series because they require
patches 2 and 4 (respectively) in order to apply cleanly.

Note that this series is based on mainline as the binding patches require
086e9074f52f ("dt-bindings: Remove more cases of 'allOf' containing a '$ref'")
in order to apply cleanly.
