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 Signed-off-by: David Heidelberg <[email protected]> --- 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/[email protected] 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/[email protected] 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/[email protected] --- David Heidelberg (7): Input: stmfts - Fix the MODULE_LICENSE() string Input: stmfts - Use dev struct directly Input: stmfts - Switch to devm_regulator_bulk_get_const Input: stmfts - abstract reading information from the firmware Input: stmfts - disable regulators when power on fails dt-bindings: input: touchscreen: st,stmfts: Introduce reset GPIO dt-bindings: input: touchscreen: st,stmfts: Introduce STM FTS5 Petr Hodina (4): Input: stmfts - use client to make future code cleaner Input: stmfts - add optional reset GPIO support Input: stmfts - support FTS5 arm64: dts: qcom: sdm845-google: Add STM FTS touchscreen support .../bindings/input/touchscreen/st,stmfts.yaml | 19 +- .../arm64/boot/dts/qcom/sdm845-google-blueline.dts | 19 +- arch/arm64/boot/dts/qcom/sdm845-google-common.dtsi | 2 +- drivers/input/touchscreen/stmfts.c | 601 +++++++++++++++++++-- 4 files changed, 580 insertions(+), 61 deletions(-) --- base-commit: db7efce4ae23ad5e42f5f55428f529ff62b86fab change-id: 20260214-stmfts5-b47311fbd732 Best regards, -- David Heidelberg <[email protected]>
