| 3 | Required properties: |
| 4 | - compatible: "mediatek,mt6397-regulator" |
| 5 | - mt6397regulator: List of regulators provided by this controller. It is named |
| 6 | according to its regulator type, buck_<name> and ldo_<name>. |
| 7 | The definition for each of these nodes is defined using the standard binding |
| 8 | for regulators at Documentation/devicetree/bindings/regulator/regulator.txt. |
| 9 | |
| 10 | The valid names for regulators are:: |
| 11 | BUCK: |
| 12 | buck_vpca15, buck_vpca7, buck_vsramca15, buck_vsramca7, buck_vcore, buck_vgpu, |
| 13 | buck_vdrm, buck_vio18 |
| 14 | LDO: |
| 15 | ldo_vtcxo, ldo_va28, ldo_vcama, ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, |
| 16 | ldo_vemc3v3, ldo_vgp1, ldo_vgp2, ldo_vgp3, ldo_vgp4, ldo_vgp5, ldo_vgp6, |
| 17 | ldo_vibr |
| 18 | |
| 19 | BUCK regulators can set regulator-initial-mode and regulator-allowed-modes to |
| 20 | values specified in dt-bindings/regulator/mediatek,mt6397-regulator.h |
| 21 | |
