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