MediaTek MT6380 Regulator



All voltage regulators provided by the MT6380 PMIC are described as the

subnodes of the MT6380 regulators node. Each regulator is named according

to its regulator type, buck-<name> and ldo-<name>. The definition for each

of these nodes is defined using the standard binding for regulators at

Documentation/devicetree/bindings/regulator/regulator.txt.



The valid names for regulators are:

BUCK:

  buck-core1, buck-vcore, buck-vrf

LDO:

  ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt



Example:



	regulators {

		compatible = "mediatek,mt6380-regulator";



		mt6380_vcpu_reg: buck-vcore1 {

			regulator-name = "vcore1";

			regulator-min-microvolt = < 600000>;

			regulator-max-microvolt = <1393750>;

			regulator-ramp-delay = <6250>;

			regulator-always-on;

			regulator-boot-on;

		};



		mt6380_vcore_reg: buck-vcore {

			regulator-name = "vcore";

			regulator-min-microvolt = <600000>;

			regulator-max-microvolt = <1393750>;

			regulator-ramp-delay = <6250>;

		};



		mt6380_vrf_reg: buck-vrf {

			regulator-name = "vrf";

			regulator-min-microvolt = <1200000>;

			regulator-max-microvolt = <1575000>;

			regulator-ramp-delay = <0>;

			regulator-always-on;

			regulator-boot-on;

		};



		mt6380_vm_reg: ldo-vm {

		};



		mt6380_va_reg: ldo-va {

			regulator-ramp-delay = <0>;

			regulator-always-on;

			regulator-boot-on;

		};



		mt6380_vddr_reg: ldo-vddr {

			regulator-name = "vddr";

			regulator-min-microvolt = <1240000>;

			regulator-max-microvolt = <1840000>;

			regulator-ramp-delay = <0>;

			regulator-always-on;

			regulator-boot-on;

		};

			regulator-name = "vt";

			regulator-min-microvolt = <2200000>;

			regulator-max-microvolt = <3300000>;

			regulator-ramp-delay = <0>;

			regulator-always-on;

			regulator-boot-on;
