Please use subject lines reflecting the style for the subsystem.

Hi , Mark

do you mean should i use "dt-bindings: regulator: mediatek" similarly as
the prefix instead of the one i currently use ? If so , i will improve
this in the next version.

No, drop the dt-bindings bit.

+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
+
+Example:
+
+	regulators {
+		compatible = "mediatek,mt6380-regulator";
+
+		mt6380_vcpu_reg: buck-vcore1 {
+			regulator-name = "vcore1";

+			regulator-name = "vrf";
