| 3 | All voltage regulators are defined as subnodes of the regulators node. A list |
| 4 | of regulators provided by this controller are defined as subnodes of the |
| 5 | PMIC's node. Each regulator is named according to its regulator type, |
| 6 | buck_<name> and ldo_<name>. The definition for each of these nodes is defined |
| 7 | using the standard binding for regulators at |
| 8 | Documentation/devicetree/bindings/regulator/regulator.txt. |
| 9 | |
| 10 | The valid names for regulators are:: |
| 11 | BUCK: |
| 12 | buck_vproc, buck_vsys, buck_vpa |
| 13 | LDO: |
| 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 |
