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
