[PATCH v8 0/2] Add support for sound profile switching and leverage for OnePlus slider

[David Heidelberg via B4 Relay]

This series add initial support for OnePlus 6 and 6T, but other OnePlus
phones contains same mechanism to switch sound profiles.

This code was tested for two years within the downstream Snapdragon 845 tree.
It is now perfectly integrated with feedbackd in the Phosh environment.

The series is also available (until merged) at
  https://gitlab.com/sdm845/sdm845-next/-/commits/b4/op6-tri-state

Changes in v8:
- Rebased against next-20251113
- Added R-b, T-b trailers from v7.
- Link to v7: https://lore.kernel.org/r/20251014-op6-tri-state-v7-0-938a6367197b@ixit.cz

Changes in v7:
- Separated GPIO number fix from the original commit
  "arm64: dts: qcom: sdm845-oneplus: Add alert-slider"
- Rebased again next-20251008
- Link to v6: https://lore.kernel.org/r/20250731-op6-tri-state-v6-0-569c25cbc8c2@ixit.cz

Changes in v6:
- Rebased again next-20250731, otherwise just a resent.
- Link to v5: https://lore.kernel.org/r/20250419-op6-tri-state-v5-0-443127078517@ixit.cz

Changes in v5:
- Dropped merged
  "Input: gpio-keys - add support for linux,input-value DTS property"
- Link to v4: https://lore.kernel.org/all/cover.1677022414.git.soyer@irl.hu/

Changes in v4:
- DTS: use default debounce-interval, order alphabetically
- Link to v3: https://lore.kernel.org/lkml/cover.1676850819.git.soyer@irl.hu/

Changes in v3:
- rename tri-state-key to alert-slider, fix DTS warnings,

Changes in v2:
- rebase to qcom/for-next
add SND_PROFILE_* identifiers to input-event-codes.h

[PATCH v8 1/2] Input: add ABS_SND_PROFILE

[David Heidelberg via B4 Relay]

From: Gergo Koteles <soyer@irl.hu>

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 v8 2/2] arm64: dts: qcom: sdm845-oneplus: Add alert-slider

[David Heidelberg via B4 Relay]

From: Gergo Koteles <soyer@irl.hu>

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.
