Subject: [PATCH v4 10/27] input: max77693: add max77705 haptic support
Add support for haptic controller on MAX77705 Multifunction
device.
This driver supports external pwm and LRA (Linear Resonant Actuator) motor.
User can control the haptic device via force feedback framework.
Signed-off-by: Dzmitry Sankouski <dsankouski@...il.com>
