1 | Mediatek MT6397 Regulator Driver |
2 | ||
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 | |
