1 MediaTek MT6358 Regulator
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.
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,
18 ldo_vcn33_bt, ldo_vcn33_wifi, ldo_vcama2, ldo_vmc, ldo_vldo28, ldo_vaud28,
19 ldo_vsim2
