- 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;
- };
- };
