··· 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, 18 + 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";
