|
|
||
| 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 | ||
