| 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 |
