1MediaTek MT6380 Regulator 2 3All voltage regulators provided by the MT6380 PMIC are described as the 4subnodes of the MT6380 regulators node. Each regulator is named according 5to its regulator type, buck-<name> and ldo-<name>. The definition for each 6of these nodes is defined using the standard binding for regulators at 7Documentation/devicetree/bindings/regulator/regulator.txt. 8 9The valid names for regulators are: 10BUCK: 11 buck-core1, buck-vcore, buck-vrf 12LDO: 13 ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt 14 15Example: 16 17 regulators { 18 compatible = "mediatek,mt6380-regulator"; 19 20 mt6380_vcpu_reg: buck-vcore1 { 21 regulator-name = "vcore1"; 22 regulator-min-microvolt = < 600000>; 23 regulator-max-microvolt = <1393750>; 24 regulator-ramp-delay = <6250>; 25 regulator-always-on; 26 regulator-boot-on; 27 }; 28 29 mt6380_vcore_reg: buck-vcore { 30 regulator-name = "vcore"; 31 regulator-min-microvolt = <600000>; 32 regulator-max-microvolt = <1393750>; 33 regulator-ramp-delay = <6250>; 34 }; 35 36 mt6380_vrf_reg: buck-vrf { 37 regulator-name = "vrf"; 38 regulator-min-microvolt = <1200000>; 39 regulator-max-microvolt = <1575000>; 40 regulator-ramp-delay = <0>; 41 regulator-always-on; 42 regulator-boot-on; 43 }; 44 45 mt6380_vm_reg: ldo-vm { 46 regulator-name = "vm"; 47 regulator-min-microvolt = <1050000>; 48 regulator-max-microvolt = <1400000>; 49 regulator-ramp-delay = <0>; 50 regulator-always-on; 51 regulator-boot-on; 52 }; 53 54 mt6380_va_reg: ldo-va { 55 regulator-name = "va"; 56 regulator-min-microvolt = <2200000>; 57 regulator-max-microvolt = <3300000>; 58 regulator-ramp-delay = <0>; 59 regulator-always-on; 60 regulator-boot-on; 61 }; 62 63 mt6380_vphy_reg: ldo-vphy { 64 regulator-name = "vphy"; 65 regulator-min-microvolt = <1800000>; 66 regulator-max-microvolt = <1800000>; 67 regulator-ramp-delay = <0>; 68 regulator-always-on; 69 regulator-boot-on; 70 }; 71 72 mt6380_vddr_reg: ldo-vddr { 73 regulator-name = "vddr"; 74 regulator-min-microvolt = <1240000>; 75 regulator-max-microvolt = <1840000>; 76 regulator-ramp-delay = <0>; 77 regulator-always-on; 78 regulator-boot-on; 79 }; 80 81 mt6380_vt_reg: ldo-vt { 82 regulator-name = "vt"; 83 regulator-min-microvolt = <2200000>; 84 regulator-max-microvolt = <3300000>; 85 regulator-ramp-delay = <0>; 86 regulator-always-on; 87 regulator-boot-on; 88 }; 89 }; 90
