This is based on work from: Jonathan Marek from qcom,pwm-vibrator.c in the PostmarketOS repo: https://gitlab.com/postmarketOS/linux-postmarketos/commit/7647fb36cb1cbd060f8b52087a68ab93583292b5 Jongrak Kwon and Devin Kim from msm_pwm_vibrator.c in the downstream Android 3.4.0 sources: https://android.googlesource.com/kernel/msm/+/android-msm-lenok-3.10-lollipop-wear-release/drivers/misc/msm_pwm_vibrator.c Driver was tested on a LG Nexus 5 (hammerhead) phone using rumble-test: https://git.collabora.com/cgit/user/sre/rumble-test.git/plain/rumble-test.c Changes since v2 - Moved from pwm to input subsystem based on feedback from https://lore.kernel.org/lkml/20181012114749.GC31561@ulmo/. I previously wired this into the input system via pwm-vibra. Changes since v1 - Update device tree binding document based on feedback from Rob Herring. - Changed the driver description to: Qualcomm PWM driver for the MSM vibrator.
