MediaTek MT6380 Regulator
|
|
|
|
All voltage regulators provided by the MT6380 PMIC are described as the
|
|
subnodes of the MT6380 regulators node. Each regulator 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-core1, buck-vcore, buck-vrf
|
|
LDO:
|
|
ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt
|
|
|
|

|
|
|
|
