[PATCH v3 1/3] Input: gpio-keys - add support for linux,input-value DTS property

[Gergo Koteles]

Allows setting the value of EV_ABS events from DTS.
This property is included in the gpio-keys.yaml scheme, but was only
implemented for gpio-keys-polled.

[PATCH v3 2/3] Input: add ABS_SND_PROFILE

[Gergo Koteles]

ABS_SND_PROFILE used to describe the state of a multi-value sound profile
switch. This will be used for the alert-slider on OnePlus phones or other
phones.

Profile values added as SND_PROFLE_(SILENT|VIBRATE|RING) identifiers
to input-event-codes.h so they can be used from DTS.

[PATCH v3 3/3] arm64: dts: qcom: sdm845-oneplus: add alert-slider

[Gergo Koteles]

The alert-slider is a tri-state sound profile switch found on the OnePlus 6,
Android maps the states to "silent", "vibrate" and "ring". Expose them as
ABS_SND_PROFILE events.
The previous GPIO numbers were wrong. Update them to the correct
ones.

Is there a reason it can't be the default 5ms, since it should
more or less be a simple input ping to the userspace?

Other than that:

Yes, it's a simple input ping to the userspace.
It works with the default 5ms also.
