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: https://youtu.be/k_vMRQiHLgA Patches 3 and 4 add support for the device's available OTP variants, which trade features or exhibit errata that require workarounds. Patch 5 represents a minor fix that is included in the series because it requires patch 2 in order to apply cleanly. This series is being resent with a previous patch 6 ("input: iqs269a: Disable channels before configuring them") dropped, as a more optimal workaround that prevents GPIO3 from inadvertently toggling during calibration has since been highlighted. If found to be viable, it will be sent as a future patch. 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.
