1Mediatek MT6323 Regulator 2 3All voltage regulators are defined as subnodes of the regulators node. A list 4of regulators provided by this controller are defined as subnodes of the 5PMIC's node. Each regulator is named according to its regulator type, 6buck_<name> and ldo_<name>. The definition for each of these nodes is defined 7using the standard binding for regulators at 8Documentation/devicetree/bindings/regulator/regulator.txt. 9 10The valid names for regulators are:: 11BUCK: 12 buck_vproc, buck_vsys, buck_vpa 13LDO: 14 ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama, 15 ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2, 16 ldo_vgp3, ldo_vcn18, ldo_vsim1, ldo_vsim2, ldo_vrtc, ldo_vcamaf, ldo_vibr, 17 ldo_vrf18, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio 18 19Example: 20 21 pmic: mt6323 { 22 mt6323regulator: regulators { 23 mt6323_vproc_reg: buck_vproc{ 24 regulator-name = "vproc";
