Subject: [PATCH v2 0/3] treewide: add vibrator support for various MSM SOCs

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 v1
- Update device tree binding document based on feedback from Rob
  Herring.
- Changed the driver description to: Qualcomm PWM driver for the MSM
  vibrator.

Brian Masney (3):
  dt-bindings: pwm: msm-vibrator: new bindings for MSM vibrator PWM
  pwm: msm-vibrator: new driver for the vibrator found on various MSM
    SOCs
  ARM: dts: qcom: msm8974-hammerhead: add device tree bindings for
    vibrator
