[PATCH v4 00/11] Input: support for STM FTS5

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

Used on various phones. Minimal viable driver.

Includes device-tree enabling touchscreen on Pixel 3.

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

Changes in v4:
- Wrap everything below enabling the supplies into stmfts_configure()
  to avoid bunch of gotos to power off on error (Dmitry T.)
- Finished chip specific ops and removed is_fts5. (Dmitry T.)
- Link to v3: https://lore.kernel.org/r/20260403-stmfts5-v3-0-5da768cfd201@ixit.cz

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@ixit.cz

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@ixit.cz
