Mediatek MT6397 Regulator Driver | ||
|
||
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 | ||
