| 2 | |
| 3 | All voltage regulators provided by the MT6380 PMIC are described as the |
| 4 | subnodes of the MT6380 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-core1, buck-vcore, buck-vrf |
| 12 | LDO: |
| 13 | ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt |
| 14 | |
