[PATCH] regulator: dt-bindings: Convert mediatek,mt6380-regulator to DT schema

Rob Herring (Arm) robh at kernel.org
Tue Sep 22 12:55:01 PDT 2026


Convert the MediaTek mediatek,mt6380-regulator binding to DT schema
format. It's a straight forward conversion.

The regulators are part of the "pwrap" block, so add a $ref to them.

-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:
-

-		mt6380_vcpu_reg: buck-vcore1 {
-			regulator-name = "vcore1";
