Use "vibrator" as node name then as per https://github.com/devicetree-org/devicetree-specification/blob/main/source/chapter2-devicetree-basics.rst?plain=1#L299 Apart from this I don't see anything wrong.

Samsung Galaxy Grand 2 is a phone based on MSM8226. It's similar to the other Samsung devices based on MSM8226 with only a few minor differences. The device trees contain initial support with: - GPIO keys - Regulator haptic - SDHCI (internal and external storage) - UART (on USB connector via the TI TSU6721 MUIC) - Regulators - Touchscreen - Accelerometer Signed-off-by: Raymond Hackley <raymondhackley@protonmail.com> --- arch/arm/boot/dts/qcom/Makefile | 1 + .../dts/qcom/qcom-msm8226-samsung-ms013g.dts | 386 ++++++++++++++++++ 2 files changed, 387 insertions(+) create mode 100644 arch/arm/boot/dts/qcom/qcom-msm8226-samsung-ms013g.dts
