1 MediaTek MT6380 Regulator
2
3 All voltage regulators provided by the MT6380 PMIC are described as the
4 subnodes of the MT6380 regulators node. Each regulator is named according
5 to its regulator type, buck-<name> and ldo-<name>. The definition for each
6 of these nodes is defined using the standard binding for regulators at
7 Documentation/devicetree/bindings/regulator/regulator.txt.
8
9 The valid names for regulators are:
10 BUCK:
11 buck-core1, buck-vcore, buck-vrf
12 LDO:
13 ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt
