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 Signed-off-by: David Heidelberg --- 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.
