Subject: [PATCH 1/2] regulator: dt-bindings: cros-ec: Add regulator supply
Date: Fri, 20 Mar 2026 16:31:32 +0800 [thread overview]
Message-ID: <20260320083135.2455444-2-wenst@chromium.org> (raw)
In-Reply-To: <20260320083135.2455444-1-wenst@chromium.org>
Even a regulator remotely controlled by the EC will have a power supply
input.
Add a property to describe the power supply input.
