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
