[PATCH v3 0/3] ARM: qcom: add vibrator support for various MSM SOCs

From: Brian Masney
Date: Wed Oct 24 2018 - 21:29:52 EST


This patch set adds support for the vibrator found on various Qualcomm
MSM SOCs. 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.
