Input: aw86927 - add support for Awinic AW86938

2026-04-01T16:08:33+00:00

Add support for the I2C-connected Awinic AW86938 LRA haptic controller. The AW86938 has a similar but slightly different register layout. In particular, the boost mode register values. The AW86938 also has some extra features that aren't implemented in this driver yet.

Input: aw86927 - respect vibration magnitude levels

2026-04-01T16:08:32+00:00

Previously the gain value was hardcoded. Take the magnitude passed via the input API and configure the gain register accordingly. Signed-off-by: Griffin Kroah-Hartman Link: https://patch.msgid.link/20260302-aw86938-driver-v4-1-92c865df9cca@fairphone.com Signed-off-by: Dmitry Torokhov

Input: aw86927 - fix error code in probe()

2025-09-30T20:19:53+00:00

Fix this copy and paste bug. Return "err" instead of PTR_ERR(haptics->regmap). Fixes: 52e06d564ce6 ("Input: aw86927 - add driver for Awinic AW86927") Signed-off-by: Dan Carpenter Link: https://lore.kernel.org/r/aNvMPTnOovdBitdP@stanley.mountain Signed-off-by: Dmitry Torokhov

Input: aw86927 - add driver for Awinic AW86927

2025-09-28T04:51:52+00:00

Add support for the I2C-connected Awinic AW86927 LRA haptic driver. This driver includes a hardcoded sine waveform to be uploaded to the AW86927's SRAM for haptic playback. This driver does not currently support all the capabilities of the AW86927, such as F0 calibration, RTP mode, and CONT mode.
