This device supports I2C only.

Required properties:

  - compatible : "richtek,rt5033-safeldo", compatible = "richtek,rt5033-ldo1", compatible = "richtek,rt5033-dcdc1"


Optional properties:

  - TBD


Example:

	i2c@78ba000 {
		rt5033-mfd@34{
		
			rt5033_safe_ldo {
				compatible = "richtek,rt5033-safeldo";
				regulator-name = "RT5033SafeLDO"; /* constraints->name, change name by yourself*/
				regulator-min-microvolt = <3300000>;
				regulator-max-microvolt = <4950000>; /* max == min then apply_uV = 1 */
				/* regulator-microvolt-offset = < >; optional*/
				/* regulator-boot-on = "yes"; optional, exist = enabled */
				regulator-always-on = "yes";
				/* regulator-ramp-delay = <100>; optional*/

			};
