- Mediatek MT6397 Regulator Driver
- Required properties:
- - compatible: "mediatek,mt6397-regulator"
- - mt6397regulator: List of regulators provided by this controller. It 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_vpca15, buck_vpca7, buck_vsramca15, buck_vsramca7, buck_vcore, buck_vgpu,
- buck_vdrm, buck_vio18
- LDO:
- ldo_vtcxo, ldo_va28, ldo_vcama, ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch,
- ldo_vemc3v3, ldo_vgp1, ldo_vgp2, ldo_vgp3, ldo_vgp4, ldo_vgp5, ldo_vgp6,
- ldo_vibr
