| Mediatek MT6323 Regulator Driver |
| |
| 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 |
