Mediatek MT6323 Regulator All voltage regulators are defined as subnodes of the regulators node. A list of regulators provided by this controller are defined as subnodes of the PMIC's 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_vproc, buck_vsys, buck_vpa LDO: ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama, ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2, ldo_vgp3, ldo_vcn18, ldo_vsim1, ldo_vsim2, ldo_vrtc, ldo_vcamaf, ldo_vibr, ldo_vrf18, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio Example: pmic: mt6323 { mt6323regulator: regulators { mt6323_vproc_reg: buck_vproc{ regulator-name = "vproc";
