arm64: dts: msm8916-samsung-a2015: Add vibrator
Commit Message
From: Nikita Travkin <nikita@trvn.ru>
Both a2015 devices use motor drivers controlled with PWM signal.
A5 additionally has a fixed regulator that powers the driver and is
controlled by enable signal. A3 routes that enable signal to the
motor driver itself.
To simplify the description, add the motor to the common dtsi and
assume a regulator is used for both.
