   1 MediaTek MT6358 Regulator
   2
   3 All voltage regulators provided by the MT6358 PMIC are described as the
   4 subnodes of the MT6358 regulators node. Each regulator is named according
   5 to its regulator type, buck_<name> and ldo_<name>. The definition for each
   6 of these nodes is defined using the standard binding for regulators at
   7 Documentation/devicetree/bindings/regulator/regulator.txt.
   8
   9 The valid names for regulators are::
  10 BUCK:
  11   buck_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
  12   buck_vs2, buck_vmodem, buck_vs1
  13 LDO:
  14   ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
  15   ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
  16   ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, ldo_vmch, ldo_vbif28,
  17   ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, ldo_vrf18,
