From e0a6590d8ceb7d6c4e35b5b5eb368d9fb800487f Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Thu, 27 Apr 2023 22:34:29 +0200 Subject: [PATCH] ARM: dts: qcom: msm8974-hammerhead: Add vibrator The Nexus 5 has a vibrator connected to the clock output of GP1_CLK which we can use with the clk-pwm driver, then we can use that pwm with pwm-vibrator to get haptics functionality. This patch is based on Brian Masney's previous patch with clk-vibrator.
