From 5ffe618764a36c2d259674b854abd574790ea56b Mon Sep 17 00:00:00 2001 From: Nikita Travkin Date: Thu, 20 Oct 2022 11:56:08 +0000 Subject: arm64: dts: qcom: msm8916-samsung-a2015: Add vibrator 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.
