  18 +All voltage regulators are defined as subnodes of the regulators node. A list
  19 +of regulators provided by this controller are defined as subnodes of the
  20 +PMIC's node. Each regulator is named according to its regulator type,
  21 +buck_<name> and ldo_<name>. The definition for each of these nodes is defined
  22 +using the standard binding for regulators at
  23 +Documentation/devicetree/bindings/regulator/regulator.txt.
  24 +
  25 +The valid names for regulators are::
  26 +BUCK:
  27 +  buck_vproc, buck_vsys, buck_vpa
  28 +LDO:
  29 +  ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
  30 +  ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,
  31 +  ldo_vgp3, ldo_vcn18, ldo_vsim1, ldo_vsim2, ldo_vrtc, ldo_vcamaf, ldo_vibr,
  32 +  ldo_vrf18, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio
  33 +
