Mediatek MT6357 Regulator Driver Required properties: - compatible: "mediatek,mt6357-regulator" - mt6357regulator: List of regulators provided by this controller. It is named according to its regulator type, buck_ and ldo_. The definition for each of these nodes is defined using the standard binding for regulators at Documentation/devicetree/bindings/regulator/regulator.txt. Optional properties in the sub-node: - mediatek,oc-irq-enable-delay-ms: Time to delay in milliseconds between re-enable over current interrupt after it triggered and be disabled. If it's not specified, the default value of this property is set to 10. The valid names for regulators are: BUCK: buck_vs1, buck_vmodem, buck_vcore, buck_vproc, buck_vpa LDO: ldo_vfe28, ldo_vxo22, ldo_vrf18, ldo_vrf12, ldo_vefuse, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_vcn28, ldo_vcn18, ldo_vcama, ldo_vcamd, ldo_vcamio, ldo_vldo28, ldo_vsram_others, ldo_vsram_proc, ldo_vaux18, ldo_vaud28, ldo_vio28, ldo_vio18, ldo_vdram, ldo_vmc, ldo_vmch, ldo_vemc, ldo_vsim1, ldo_vsim2, ldo_vibr, ldo_vusb33 Example: pmic { compatible = "mediatek,mt6357";
