Subject: [PATCH 11/13] arm64: dts: mediatek: mt8195-cherry: Fix VBUS regulator description
Date: Fri, 20 Mar 2026 16:43:43 +0800	[thread overview]
Message-ID: <20260320084351.2461060-12-wenst@chromium.org> (raw)
In-Reply-To: <20260320084351.2461060-1-wenst@chromium.org>

The VBUS regulator is a current-limiting switch. It does not have
voltage regulation capabilities. The description is also missing a power
input.

Drop the voltage constraints, and add a supply input.
