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_vcore_sshub, buck_vpa, buck_vproc11, 12 buck_vproc12, buck_vgpu, 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_others_sshub, ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, 17 ldo_vmch, ldo_vbif28, ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, 18 ldo_vrf18, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_vcama2, ldo_vmc, ldo_vldo28, ldo_vaud28, 19 ldo_vsim2 20 21 Example: 22 23 pmic { 24 compatible = "mediatek,mt6358";
