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 {
			regulator-name = "vm";
			regulator-min-microvolt = <1050000>;
			regulator-max-microvolt = <1400000>;
			regulator-ramp-delay = <0>;
			regulator-always-on;
			regulator-boot-on;
		};

		mt6380_va_reg: ldo-va {
			regulator-name = "va";
			regulator-min-microvolt = <2200000>;
			regulator-max-microvolt = <3300000>;
			regulator-ramp-delay = <0>;
			regulator-always-on;
			regulator-boot-on;
		};

		mt6380_vphy_reg: ldo-vphy {
			regulator-name = "vphy";
			regulator-min-microvolt = <1800000>;
			regulator-max-microvolt = <1800000>;
			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;
		};

		mt6380_vt_reg: ldo-vt {
			regulator-name = "vt";
			regulator-min-microvolt = <2200000>;
			regulator-max-microvolt = <3300000>;
			regulator-ramp-delay = <0>;
			regulator-always-on;
			regulator-boot-on;
		};
