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
