Subject: [PATCH] regulator: dt-bindings: Convert mediatek,mt6380-regulator to DT schema
Date: Tue, 22 Sep 2026 14:55:01 -0500 [thread overview]
Message-ID: <20260922195502.818012-1-robh@kernel.org> (raw)
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.
Assisted-by: LLM

-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
-
