[PATCH v2 0/4] 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.

The original series was first introduced in [1]. Patch 5 was determined to be
non-optimal, and has since been dropped. Patch 6 has been dropped in favor of
[2] which has since been merged.
