[PATCH WIP v2 00/11] Input: support for STM FTS5

[David Heidelberg via B4 Relay]

Used on various phones. Minimal basic support.

Includes device-tree enabling touchscreen on Pixel 3.

Sending as WIP, as not all comments we're addressed, but please to apply
any patch which does look ready for inclusion.

What is missing:
 - firmware loading
 - switching between AP and SLPI mode (to wake up phone by touch)
 - anything above basic touch

TODO for v3:
- wrap everything below enabling the supplies into stmfts_configure()
  to avoid bunch of gotos to power off on error? (Dmitry T.)
- finish chip specific ops and potentinally remove is_fts5. (Dmitry T.)
Changes in v2:
- Fix typo in the binding s/switch-gpio/switch-gpios/.
- Deduplacate allOf. (Rob yamllint)
- Add missing S-off-by. (Dmitry B.)
- Dropped irq-gpios as it's not needed. (Konrad)
- Correct x and y touchscreen area size. (Konrad)
- Correct reset introduction commit description. (Krzysztof)
- Partially implemented chip specific ops. (Dmitry T.)
- Separeted license naming cleanup into separate commit (Dmitry T.)
- Link to v1: https://lore.kernel.org/r/20260301-stmfts5-v1-0-22c458b9ac68@xxxxxxx
