This patch series exposes it via input subsystem (EV_FF). I'd like to ask input maintainers to take the patches 1 and 2. Patches 3 and 4 should go via the sunxi tree. The change to the vibrator driver is meant to enable toggling the vibrator motor just via a power supply itself. There's not additional gpio driven switch on this tablet between the power supply for the motor and the motor. Please take a look. Changes in v5: - Fix probe without a power supply (Dmitry) Changes in v4: - Added DT reviewed-by tag - Fixed motor typo Changes in v3: - Changed dt-binding to require at least one of enable/supply, dropped ack - Changed driver to bail out if neither supply nor gpio is given Changes in v2: - Added DT ack tag - Add more information to the commit log (re use of LDO for the power) thank you and regards, Ondrej Jirman Ondrej Jirman (4): dt-bindings: input: gpio-vibrator: Don't require enable-gpios input: gpio-vibra: Allow to use vcc-supply alone to control the vibrator ARM: dts: sun8i-a83t-tbs-a711: Add support for the vibrator motor ARM: dts: sun8i-a83t-tbs-a711: Increase voltage on the vibrator .../bindings/input/gpio-vibrator.yaml | 7 ++++++- arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts | 9 +++++++-- drivers/input/misc/gpio-vibra.c | 18 +++++++++++++----- 3 files changed, 26 insertions(+), 8 deletions(-)
