MediaTek MT6358 Regulator
All voltage regulators provided by the MT6358 PMIC are described as the
subnodes of the MT6358 regulators 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_vdram1, buck_vcore, buck_vcore_sshub, buck_vpa, buck_vproc11,
buck_vproc12, buck_vgpu, buck_vs2, buck_vmodem, buck_vs1
LDO:
ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
ldo_vsram_others_sshub, ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18,
ldo_vmch, ldo_vbif28, ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12,
ldo_vrf18, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_vcama2, ldo_vmc, ldo_vldo28, ldo_vaud28,
ldo_vsim2
