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
