| 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_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_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 |
