Subject: [PATCH v4 11/12] regulator: mt6358: Add supply names for MT6366 regulators
Date:   Thu, 28 Sep 2023 16:55:34 +0800
Message-ID: <20230928085537.3246669-12-wenst@chromium.org>
In-Reply-To: <20230928085537.3246669-1-wenst@chromium.org>
References: <20230928085537.3246669-1-wenst@chromium.org>

The DT bindings for MT6366 regulator defines the supply names for the
PMIC.

Add support for them by adding .supply_name field settings for each
regulator. The buck regulators each have their own supply whose name
can be derived from the regulator name. The LDOs have shared supplies.
