[PATCH WIP v3 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 feel
free to apply any patch which does look ready for inclusion.

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

TODO for v4:
- 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 v3:
- s/touchscreen_pins/touchscreen_irq_n. (Konrad)
- Use interrupts-extended. (Konrad)
- Fixed rebase conflict against 8665ceb926ec ("Input: stmfts - use guard notation when acquiring mutex")
- Rename switch-gpios to mode-switch-gpios.
- Do not define properties in if:then: branches. (Krzysztof)
- Link to v2: https://lore.kernel.org/r/20260315-stmfts5-v2-0-70bc83ee9591@xxxxxxx

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
