	This attribute is only present if ``intel_pstate`` works in the

Required properties:

- compatible: should be "sprd,sc2731-vibrator".

- reg: address of vibrator control register.



Example :



	sc2731_pmic: pmic@0 {

		compatible = "sprd,sc2731";

		reg = <0>;

		spi-max-frequency = <26000000>;

		interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;

		#size-cells = <0>;
