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
