1 Mediatek MT6397 Regulator
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.

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
